cmd/cli: split-route SRV record to OS resolver
...
Since SRV record is mostly useful in AD environment. Even in non-AD one,
the OS resolver could still resolve the query for external services.
Users who want special treatment can still specify domain rules to
forward requests to ControlD upstreams explicitly.

So ctrld can record the raw/original client IP instead of looking up
from MAC to IP, which may not the right choice in some network setup
like using wireguard/vpn on Merlin router.
