Rusty Russell d29795a198 connectd: don't just close to peer, but use shutdown().
We would lose packets sometimes due to this previously, but it
doesn't happen over localhost so our tests didn't notice.  However,
now we have connectd being sole thing talking to peers, we can do
a more elegant shutdown, which should fix closing.

Changelog-Fixed: Protocol: Always flush sockets to increase chance that final message get to peer (esp. error packets).
