[PATCH] xfs/288: _notrun if xfs_db write doesn't support -d option

[Zorro Lang <zlang@redhat.com>]

Commit b3cf8b72334fd35ef961869506e5a72ab398bc82 help xfs/288 to
support v5 filesystems testing, but there're still some old
distributions don't support xfs_db 'write -d' usage. Then this
case fails on them.

For compatible with older versions, skip this test on v5 xfs
if xfs_db write command doesn't support -d option.
