    Fix http sharing not workin on Linux 3.0
    
    gnome-user-share tries to discover a free port to run Apache on by
    bind()ing a struct sockaddr_in with no port specified in
    src/http.c:get_port(). However, it neglects to specify an address
    family, so that attempt fails with EINVAL, and the -1 returned gets
    passed to spawn_httpd() as the port that Apache should be listening on,
    which causes to Apache promptly and silently bail.
    
    This error was caused by a regression in Linux 3.0:
