common/xfs: Check if write supports [-c|-d] option in xfs_db

Make sure _scratch_xfs_set_metadata_field() can be used on an
old xfsprogs-dev(e.g. v3.1.1).

The "-d" option was introduced since xfsprogs-dev v4.7.0 by commit
86769b3 ("xfs_db: allow recalculating CRCs on invalid metadata").

The special argument "--" is only used to end option-scanning
in getopt().  getopt() was introduced since xfsprogs-dev v3.2.3 by
commit c9f5e3d ("xfs_db: Allow writes of corrupted data")'.
