xfs/449: update test to know about xfs_db -R

The realtime groups feature added a -R flag to xfs_db so that users can
pass in the realtime device.  Since we've now modified the
_scratch_xfs_db to use this facility, we can update the test to do exact
comparisons of the xfs_db info command against the mkfs output.
