Patch to compile on gnu/hurd

[SnarkBoojum]

The Debian package for tornado has to following patch since long, but I think it was never forwarded:

I think that patch may be obsolete. We now have an except clause in bind_unix_socket to catch an error that is said to occur on hurd:

tornado/tornado/netutil.py

Lines 205 to 210 in 559f94a

	try:
	sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
	except socket.error as e:
	if errno_from_exception(e) != errno.ENOPROTOOPT:
	# Hurd doesn't support SO_REUSEADDR
	raise
