CL 163726 added workarounds to keep the iOS builders happy in
a symlinked temporary dir.
The workarounds also made the tests more realistic and improved
performance. Keep them but also handle symlinks better in the
exec wrapper.

This test currently fails in the Android builders, with the message
pkg_test.go:64: go test -short: exec: "go": executable file not found in $PATH
(https://build.golang.org/log/39ec0da5bfb7793359e199cc8e358ca5a8257840)
I was not able to test this change, because I can't get 'gomote
create' to return an instance of anything Android. However, I will
watch the build dashboard after submitting to verify that the fix
works.

We've got away with not copying the testdata directories for the

Similar to what the iOS exec wrapper does.

Android emulator builders are soon to join the trybot set. To avoid
flaky runs, work around a longstanding adb bug where concurrent adb
commands sometimes fail.
I haven't seen the problem on actual devices until recently. It seems
that the recently added "adb wait-for-device" can introduce flakyness
with errors such as:
adb: error: failed to get feature set: protocol fault (couldn't read status): Connection reset by peer
Instead of working around that, give up and serialize use of adb
everywhere.

To run the standard library tests on Android, the androidtest.bash
script copies GOROOT to the device. Move that logic to the android
exec wrapper, thereby making androidtest.bash obsolete.
Apart from making Android less special, the sharded builder

After this CL, runtime.Callers returns a pc per user frame.
runtime.CallersFrames just maps those to user frame info.

due to typedefs loaded after the first loop iteration.

The old code ignored the field alignment, and only looked at the field
offset: if the field offset required padding, cgo added padding. But
while that approach works for Go (at least with the gc toolchain) it
doesn't work for C code using packed structs. With a packed struct the
added padding may leave the struct at a misaligned position, and the
inserted alignment, which cgo is not considering, may introduce
additional, unexpected, padding. Padding that ignores alignment is not
a good idea when the struct is not packed, and Go structs are never
packed. So don't ignore alignment.
