modules: nmake dynamic ports work in link-factory

Browse source 
Just making a port and adding it to a node does not make it a working
port..

Make a new node function to get a new free port, this will actually call
the implementation spa_node_add_port(), which will add the new port
which we can then pick up and use.

See #4876
