With the change to CRCs by default, some tests are updated to call mkfs
with "-m crc=0" option directly, and this breaks testings on older
distros where mkfs.xfs doesn't have crc support.

Introduce a new variable to tell if mkfs.xfs supports v5 xfs and do
tweaks in _scratch_mkfs_xfs_opts() based on it.

This depends on Dave's commit "filter: inode size output of mkfs.xfs can change"

v3:
- move mkfs.xfs check to common/config

v2:
- use _scratch_mkfs_xfs_supported not _scratch_mkfs
- use if/else not [ ] && ... in xfs/073
