I think that's fine, at least xfs/083 and ext4/006 do grep it :)
Or we can redirect xfs_db output to a $tmp.xfs_db file and grep it, and
append the file content to $seqres.full if necessary, so that we just
grep what we care about, not the full $seqres.full file.

At first I thought this might lose test coverage with v5 filesystem, but
after looking at the xfsprogs commit that fixed the original bug (commit
198b747f2553 ("repair: properly mark lost+found inode as used")), it
seems like that both v4 and v5 go to the same code path, and we won't
lose test coverage.
If this is the case, I think it's worth mentioning it in commit log too.
Otherwise looks fine to me.
