Update RSOS extend_info_from_node calls to be direct connections
In rend_consider_services_intro_points() and find_rp_for_intro(), a RSOS calls extend_info_from_node() to get the node's address. Since it's making a direct connection, it should pass 1.
This will enforce IP address preferences and other reachable address settings once #17840 (moved) is merged.
Hidden services should continue to pass 0.
