    daemon: Don't call g_option_context_set_ignore_unknown_options
    
    When using unknown command line options with the GDM daemon, the
    program hangs until explicitly getting killed.
    
    This commit addresses that bug by dropping an unnecessary call to
    g_option_context_set_ignore_unknown_options, so GOptionContext will
    now give an error when encountering unknown options.
