generic/085 was failing on a machine w/o devicemapper kernel
support because it requires the linear target, but didn't
explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose
to go the route of a generic helper, _require_dm_target $FOO,
because some day someone will need the zero target, the error
target, or who knows.
Add the helper, use it in test generic/085, and convert
_require_dm_flakey, _require_dm_snapshot, and
_dmerror_required with this new helper.

generic tests 039, 059 and 325 need _require_metadata_journaling too,
they use dm_flakey to trigger log replay. I've seen 039 and 059 failed
post-test fsck on ext2, 325 could possibly fail too.

This test is motivated by an fsync issue discovered in btrfs.
The issue was that after fsyncing an inode that got its link count
decremented, and the new link count is greater than zero, after the
fsync log replay the inode's parent directory metadata became
inconsistent - it had a wrong i_size and dangling index entries which
prevented the directory from ever being removed (rmdir always failed
with -ENOTEMPTY, even if the directory had no more child inodes).
The btrfs issue was fixed by the following linux kernel patch:
