[PATCH V2] common/rc: improve _require_metadata_journaling() for ext4

[Eric Whitney]

The code in _require_metadata_journaling() currently rejects ext4 file
systems that have been created without a journal.  However, an ext4
file system with a journal should also be rejected if the journal is
not loaded and made available for use at mount time.

V2:  Replaced code with call to _exclude_scratch_mount_option() per
review comment.
