fix fallback when ipv6 is disabled but resolv.conf has v6 nameserves
apparently this code path was never tested, as it's not usual to have
v6 nameservers listed on a system without v6 networking support. but
it was always intended to work.
when reverting to binding a v4 address, also revert the family in the
sockaddr structure and the socklen for it. otherwise bind will just
fail due to mismatched family/sockaddr size.
