Switch query fixing aclitems in ~15 from O(N^2) to O(N) in upgrade_adapt.sql
f4f2f2b was doing a sequential scan of pg_class before checking if a
relation had attributes dependent on aclitem as data typewhen building
the set of ALTER TABLE queries, but it would be costly on a regression
database.
While on it, make the query style more consistent with the rest.
