Fix CREATE DATABASE so we can pg_upgrade DBs with OIDs above 2^31.

Commit aa0105141 repeated one of the oldest mistakes in our book:
thinking that OID is the same as int32.  It isn't of course, and
unsurprisingly the first person who came along with a database
OID above 2 billion broke it.  Repair.

Per bug #17677 from Sergey Pankov.  Back-patch to v15.
