pgsql: Remove is_index parameter from binary_upgrade_set_pg_class_oids(

Remove is_index parameter from binary_upgrade_set_pg_class_oids().

Since commit 9a974cbcba, this function retrieves the relkind before
it needs to know whether the relation is an index, so we no longer
need callers to provide this information.
