David Anderson baa7937998 net/interfaces: return IPv6 addresses from LocalAddresses.
In practice, we already provide IPv6 endpoint addresses via netcheck,
and that address is likely to match a local address anyway (i.e. no NAT66).
The comment at that piece of the code mentions needing to figure out a
good priority ordering, but that only applies to non-active-discovery
clients, who already don't do anything with IPv6 addresses.
