initdb: Set collversion for standard collation UNICODE

Since the behavior of the UNICODE collation can change with new
ICU/Unicode versions, we need to apply the versioning mechanism to it.
We do this with an UPDATE command in initdb; this is similar to how we
put the collation version into pg_database already.
