tests: change how sockets are closed
Python 3 uses a different type to represent a socket file object
than Python 2. We need to conditionalize how the socket is closed
accordingly.
While we're here, we switch to use socket.shutdown() to close the
socket. This is because socket.close() may not actually close
the socket until it is GCd. socket.shutdown() forces an immediate
shutdown.
I suspect Python 3 changed semantic behavior here, as I can't get
test-http-bad-server.t to work with socket.close(). socket.shutdown()
does appear to work, however.
