Subject: [PATCH] fix filter for stripe aligned filesystems

Flags has extra bits set in it xfs_bmap output when
the filesyste is using stripe alignment. Fix the test
to only look at the unwritten flag. Capture the xfs_bmap
output as well so failures can be debugged easily.
Merge of master-melb:xfs-cmds:30994a by kenmcd.

  fix filter for stripe aligned filesystems.
