    Drop extra listen() call in gss-server
    
    There is already call to listen in create_socket(), and there is no
    need to tie the backlog to the number of threads.  Also, here listen()
    was sometimes called with zero backlog, making gss-server execution
    (and tests) racy on slower and busy systems.
