There would be some unexpected errors when the whole TMPDIR is located
on nfs, so add a test for it in sanity.bbclass.

The better way to get the filesystem id should be get f_fsid from struct
statvfs, but there is no f_fsid in os.stat() or os.statvfs(), so we use
'stat -f -c "%t"' here.

BTW., s/tmpdir/TMPDIR/ in the previous comment message to make them have
a uniform.
