Enable deduplication in system catalog indexes.
The "equality implies image equality" opclass infrastructure disallowed
deduplication in system catalog indexes and TOAST indexes before now.
That seemed like the right approach back when the infrastructure was
added by commit 612a1ab7, since ALTER INDEX cannot set deduplicate_items
to 'off' (due to an old implementation restriction). But that decision
now seems arbitrary at best. Remove special case handling implementing
this policy.
No catversion bump, since existing catalog indexes will still work.
