net, init: derive default onion port if a user specified a -port

After port collisions are no longer tolerated but lead to
a startup failure in v28.0, local setups of multiple nodes,
each with a different -port value would not be possible anymore
due to collision of the onion default port - even if the nodes
were using tor or not interested in receiving onion inbound connections.

Fix this by deriving the onion listening port to be -port + 1.
