xfs_db requires us to pass in the log device, if any; this can be accomplished via _scratch_xfs_db_options (if we're operating on the scratch device, anyway). However, many of the tests/xfs/ scripts pass only $SCRATCH_DEV directly, so they'll fail if we test with an external log. Fix that by adding a new _scratch_xfs_db helper. Signed-off-by: Darrick J.
