    Sort the output of podify_signals in a deterministic way.
    
    The output of Glib::Type->list_signals is unsorted. This results in the
    generated pod files to be in random order which makes packages using signals
    compile not reproducibly [1].
    
    It was suggested to Glib upstream [2] to sort the output of g_signal_list_ids
    but it got rejected. Thus the change has to be made here.
