[PATCH v2] xfs/073: avoid finobt warning from mkfs

[Eryu Guan <eguan@redhat.com>]

When testing xfs/073 with MKFS_OPTIONS="-m crc=1,finobt=1" set, it fails
due to extra warning about disabling finobt feature:

 +warning: finobt not supported without CRC support, disabled.

Because xfs/073 disables crc unconditionally and finobt can not be
enabled either.

Fix it by explicitly disabling finobt as well.

Also remove all meta related mkfs options in _scratch_mkfs_xfs_opts() if
mkfs.xfs has no metadata support, not only the crc option. So that test
still passes on distros with such old binaries.

v2:
- disable finobt explicitly, instead of filtering the warning
