vnc: fix bug: vnc server can't start when 'to' is specified

commit e0d03b8ceb52 converted VNC startup to use SocketAddress,
the interface socket_listen don't have a port_offset param, so
we need to add the port offset (5900) to both 'port' and 'to' opts.
currently only 'port' is added by offset.
This patch add the port offset to 'to' opts.
