path/filepath: deflake TestEvalSymlinksAboveRoot on darwin

On darwin, under load, it appears that the system occasionally
deletes the temp dir mid-test. Don't fail the test when that happens.

It would be nice to fix this in a deeper way.
See golang.org/cl/332009 for some discussion.

In the meantime, this will at least stop the flakiness.

Updates #37910
