    gtkdoc-scan: fix regex for get_type() functions
    
    This regexp was apparently looking for "(void)" or "()" but in fact, due
    to improper order of operations, would match any declaration with either
    of "(void" or ")" in it (ie: everything).
    
    Since nobody is really doing '()' anyway, just make it match '(void)'.
    
    This fixes the inappropriate matching of g_io_extension_get_type().
