Hmm, this enables scrub after each test by default, because
$TEST_XFS_SCRUB is not checked anymore. Either remove TEST_XFS_SCRUB
completely (it's documented in README) or check it in this
_supports_xfs_scrub() helper. I'm fine with either way :)

Dump stderr to $seqres.full too? I noticed many warning messages printed
by xfs_scrub, though the tests didn't fail.
