tests: Move the non-local port as tunnel endpoint test.

Browse Source 
It's not a system test as it runs with dummy datapath and ports
and it has nothing to do with layer 3 tunnels.

It should be with other userspace tunnel tests.

While moving also making it a little nicer visually and less error
prone by requesting port numbers for all the ports.
