Andrew Dunham 16ef88754d net/portmapper: don't return unspecified/local external IPs
We were previously not checking that the external IP that we got back
from a UPnP portmap was a valid endpoint; add minimal validation that
this endpoint is something that is routeable by another host.

Updates tailscale/corp#23538
