rpc: Add listen address to incoming connections in `getpeerinfo`

This adds the listening address on which incoming connections were received to the
CNode and CNodeStats structures.

The address is reported in `getpeerinfo`.

This can be useful for distinguishing connections received on different listening ports
(e.g. when using a different listening port for Tor hidden service connections)
or different networks.
