Commit b3cf8b72334fd35ef961869506e5a72ab398bc82 help xfs/288 to
support v5 filesystems testing, but there're still some old
distributions don't support xfs_db write '-d' option, or can't
write values into dir/attr of v5 filesystems.
For compatible with older versions, skip this test on v5 xfs
if xfs_db write can't write v5 XFS dir/attr.

Hi,
Xiao found v1 can't work well on xfsprogs-4.9, due to 'write -d' can't
write vaules into dir/attr of v5 filesystems before xfsprogs-4.13.
Only check "if write command has -d option" is not enough. So I write
a function _require_xfs_db_write_da() to make sure current xfs_db
can write dir/attr (not only on v5, but especially for v5).
Thanks,
Zorro
