This commits fixes tests for AIX inside os package.
"hostname" command on AIX returns "name.domain" and not only "name".
So, "hostname -s" must be called.

This is similar to CL 136816 for x/sys/unix, changing the FreeBSD ABI to use 64-bit inodes in
Stat_t, Statfs_t, and Dirent types.
The changes are forward compatible, that is FreeBSD 10.x, 11.x continue to use their current sysnum numbers.
The affected types are converted to the new layout (with some overhead).
Thus the same statically linked binary should work using the native sysnums (without any conversion) on FreeBSD 12.
Breaking API changes in package syscall are:
Mknod takes a uint64 (C dev_t) instead of int.
Stat_t: Dev, Ino, Nlink, Rdev, Gen became uint64.
Atimespec, Mtimespec, Ctimespec, Birthtimespec renamed to Atim, Mtim, Ctim, Birthtim respectively.
Statfs_t: Mntonname and Mntfromname changed from [88]int8 to [1024]int8 arrays.
Dirent: Fileno became uint64, Namlen uint16 and an additional field Off int64 (currently unused) was added.
The following commands were run to generate ztypes_* and zsyscall_* on FreeBSD-12.0-ALPHA6 systems (GOARCH=386 were run on the same amd64 host):
GOOS=freebsd GOARCH=amd64 ./mksyscall.pl -tags freebsd,amd64 syscall_bsd.go syscall_freebsd.go syscall_freebsd_amd64.go |gofmt >zsyscall_freebsd_amd64.go
GOOS=freebsd GOARCH=amd64 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=amd64 go run mkpost.go >ztypes_freebsd_amd64.go
GOOS=freebsd GOARCH=386 ./mksyscall.pl -l32 -tags freebsd,386 syscall_bsd.go syscall_freebsd.go syscall_freebsd_386.go |gofmt >zsyscall_freebsd_386.go
GOOS=freebsd GOARCH=386 go tool cgo -godefs types_freebsd.go | GOOS=freebsd GOARCH=386 go run mkpost.go >ztypes_freebsd_386.go
GOOS=freebsd GOARCH=arm ./mksyscall.pl -l32 -arm -tags freebsd,arm syscall_bsd.go syscall_freebsd.go syscall_freebsd_arm.go |gofmt >zsyscall_freebsd_arm.go
GOOS=freebsd GOARCH=arm go tool cgo -godefs -- -fsigned-char types_freebsd.go | GOOS=freebsd GOARCH=arm go run mkpost.go >ztypes_freebsd_arm.go
The Kevent struct was changed to use the FREEBSD_COMPAT11 version always (requiring the COMPAT_FREEBSD11 kernel option FreeBSD-12, this is the default).
The definitions of ifData were not updated, their functionality in has have been replaced by vendored golang.org/x/net/route.
freebsdVersion initialization was dropped from init() in favor of a sync.Once based wrapper - supportsABI().

SameFile opens file to discover identifier and volume serial
number that uniquely identify the file. SameFile uses Windows
CreateFile API to open the file, and that works well for files
and directories. But CreateFile always follows symlinks, so
SameFile always opens symlink target instead of symlink itself.
This CL uses FILE_FLAG_OPEN_REPARSE_POINT flag to adjust
CreateFile behavior when handling symlinks.
As per https://docs.microsoft.com/en-us/windows/desktop/FileIO/symbolic-link-effects-on-file-systems-functions#createfile-and-createfiletransacted
"... If FILE_FLAG_OPEN_REPARSE_POINT is specified and:
If an existing file is opened and it is a symbolic link, the handle
returned is a handle to the symbolic link. ...".
I also added new tests for both issue #21854 and #27225.
Issue #27225 is still to be fixed, so skipping the test on
windows for the moment.
Fixes#21854
Updates #27225

Per golang/go#27524 there are situations where the username for the
uid does not match the value in the $USER environment variable and it
seems sensible to choose the value in /etc/passwd when they disagree.
This may make the Current() call slightly more expensive, since we
read /etc/passwd with cgo disabled instead of just checking the
environment. However, we cache the result of Current() calls, so we
only invoke this cost once in the lifetime of the process.

CL 129063 added a test in TestScript/mod_enabled,
which was failing on Plan 9.
The test was failing because the Init function
of the cmd/go/internal/modload package was
expecting ModRoot to be part of os.TempDir.
However, ModRoot was set to TMPDIR, while
os.TempDir is returning /tmp on Plan 9.
This change fixes the implementation of
os.TempDir on Plan 9 to handle the TMPDIR
environment variable, similarly to Unix.
