zmq: change TIPC default lookup domain when connecting

By default, TIPC uses a closest first approach to find
a publication that can satisfy your connection request.
Any publication on the local node will automatically
be chosen for all requests, even if you're trying to
spread it out over multiple machines.
We fix this by widening the default lookup scope.
