    x11/xdm: fix build with clang 16
    
    Clang 16 has a new error about incompatible function types, which shows
    up when x11/xdm:
    
      greet.c:451:20: error: incompatible function pointer types assigning to 'void (*)(void)' from 'int (*)(void)' [-Wincompatible-function-pointer-types]
          __xdm_setgrent = dlfuncs->_setgrent;
                         ^ ~~~~~~~~~~~~~~~~~~
    
    This is because it assumes setgrent(3) returns int, which it has not
    done since a very long time.
