Rewrite previous commit's test for TestUpgradeXversion compatibility.

v17 introduced the MAINTAIN ON TABLES privilege.  That changed the
applicable "baseacls" reaching buildACLCommands().  That yielded
spurious TestUpgradeXversion diffs.  Change to use a TYPES privilege.
Types have the same one privilege in all supported versions, so they
avoid the problem.  Per buildfarm.  Back-patch to v13, like that commit.
