connectd: generate message for lightningd inside peer_connected().

We used to generate this in the caller, then save it in case we needed
to retry.  We're about to change the message we send to lightningd, so
we'll need to regenerate it every time; just hand all the extra args
into peer_connected() and we can generate the `connect_peer_connected`
msg there.
