torcontrol: Use the default/standard network port for Tor hidden services, even if the internal port is set differently
Currently, the hidden service is published on the same port as the public listening port.
But if a non-standard port is configured, this can be used to guess (pretty reliably) that the public IP and the hidden service are the same node.
