Cuong Manh Le a4c1983657 cmd/ctrld: make setDNS works on system using systemd-networkd ...

On Ubuntu 18.04 VM with some cloud provider, using dbus call to set DNS
is forbidden. A possible solution is stopping networkd entirely then
using systemd-resolve to set DNS when ctrld starts.

While at it, only set DNS during start command on Windows. On other
platforms, "ctrld run" does set DNS in service mode already.

When using systemd-resolved, only change listener address to default
route interface address if a loopback address is used.

Also fixing a bug in upstream tailscale code for checking in container.
