resolved: let's preferably route reverse lookups for local subnets to matching interfaces

Let's preferably route traffic for reverse lookups to LLMNR/mDNS/DNS on
the matching interface if the IP address is in the local subnet. Also,
if looking up an IP address of our own host, let's avoid doing
LLMNR/mDNS at all.

This is useful if "~." is a routing domain to DNS, as it means, local
reverse lookups still go to LLMNR/mDNS, too.
