Fix pg_upgrade of large object permissions by preserving pg_auth.oid,

which is stored in pg_largeobject_metadata.

No backpatch to 9.0 because you can't migrate from 9.0 to 9.0 with the
same catversion (because of tablespace conflict), and a pre-9.0
migration to 9.0 has not large object permissions to migrate.
