Safely ignore exception when sock.shutdown() is called on a disconnected socket.

[nk9]

When using the smuggler tool on some sites, I was getting an error that stopped the run. Perhaps there's a way to make sure that shutdown() isn't called when the socket has already been closed. But catching and ignoring this exception seems to be effective.

 $ python3 smuggler.py -v 2 -u http://example.com                                                                                                         13:41:42
