TUN inbound: IPv6 entries in dns keep the TUN from starting on Windows when IPv6 cannot be set up, as in gateway and autoSystemRoutingTable

Follow-up to #7325: an IPv6 server in dns now asks for IPv6 as well.
When the adapter has no IPv6 interface, or refuses its IPv6 DNS servers,
the TUN fails to start instead of starting without them. Without IPv6 in
any of the three, both are still skipped: the IPv6 DNS servers that Xray
sets on every start are none then.
