io: preserve ipv4/ipv6 flags when resolving InetSocketAddress
The original InetSocketAddress struct may have has_ipv4 and
has_ipv6 fields set, which will control both the ai_family
used during DNS resolution, and later use of the V6ONLY
flag.
Currently the standalone DNS resolver code drops the
has_ipv4 & has_ipv6 flags after resolving, which means
the later bind() code won't correctly set V6ONLY.
This fixes the following scenarios
-vnc :0,ipv4=off
-vnc :0,ipv6=on
-vnc :::0,ipv4=off
-vnc :::0,ipv6=on
which all mistakenly accepted IPv4 clients
