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.

# Test that if we remove one hard link from an inode, evict the inode, fsync the
|
|
# inode, power fail and then mount the filesystem, the hard link we removed does
|
|
# not exists anymore and the filesystem metadata is in a consistent state.
