tor_addr_is_public_for_reject should return 0 for multicast addresses
This makes the treatment of addresses from other sources consistent with the implementation of get_interface_address6_list. This might need to be cherry-picked to: * legacy/trac#17027 (0.2.7) * legacy/trac#17610 (0.2.6) But only once their implementations include tor_addr_is_public_for_reject.
