Wait for POLLIN to do client tls_handshake

Otherwise a client could cause pounce to hang (since the sockets are
left blocking) by opening a connection without handshaking! Oops,
that's pretty bad. Since the sockets are still blocking, a hang can
still be caused by a client sending a partial handshake then waiting.
More fixes to follow.

pounce is slightly protected from this when used with calico, as it
applies a timeout to waiting for the ClientHello.
