Renumber pg_get_acl() in pg_proc.dat

a641707 has introduced as project policy that new features
committed during the development cycle should use new OIDs in the
[8000,9999] range.

4564f1c did not respect that rule, so let's renumber pg_get_acl()
to use an OID in the correct range.

Bump catalog version.
