This fixes the test after CL 455357, which builds the time/tzdata file
from $GOROOT/lib/time/zoneinfo.zip.

cmd/dist can't easily hard-code -buildvcs=false because not all
versions of cmd/go supported for bootstrapping recognize that flag.
However, we don't want to stamp the bootstrap binaries: the stamping
is redundant with the VERSION file writted during bootstrapping (which
is why it is normally omitted for standard-library packages and
commands), and it may also interfere with building the Go repo from a
source tarball or zip file.
Fixes#54852.

go:embed disallows using symlinked files by design.
crypto/elliptic is the first std package to use it as of CL 380475,
and unfortunately that broke the TestRepeatBootstrap long test.
The reason it uses symlinks is for speed; it wants to copy GOROOT/src,
but regular files aren't going to be modified in any way,
so a symlink, if supported, means not needing to copy the contents.
Replace the symlink attempt with hard links,
which will mean regular files remain as such, fixing go:embed.
It's worth noting that on many systems hard links won't work,
as the temporary filesystem tends to be separate,
but it doesn't hurt to try.
In my system, where /tmp is tmpfs, the test now copies more bytes.
With the added Logf, I can see overlayDir goes from ~30ms to ~100ms.
This makes sense, as GOROOT/src currently weighs around 100MiB.
To alleviate that slow-down, stop copying testdata directories,
as they currently weigh around 20MiB and aren't needed for the test.
This gets overlayDir on my system down to an acceptable ~70ms.
I briefly considered teaching overlayDir what files can be symlinks,
but that seemed fairly complex long-term, as any file could be embedded.
While here, start using testing.T.TempDir and fs.WalkDir.
For #50995.

This test is slow and resource-intensive, and will rarely catch
failures. It is important to run sometimes, but probably a waste of
time on smaller (and especially reverse) builders.
Rather than hard-coding a list of small builders, only run it on the
longtest builders.
