    Ignore MAP_VARIABLE in tst-mman-consts.py
    
    Linux 6.2 removed the hppa compatibility MAP_VARIABLE define.  That
    means that, whether or not we remove it in glibc, it needs to be
    ignored in tst-mman-consts.py (since this macro comparison
    infrastructure expects that new kernel header versions only add new
    macros, not remove old ones).
    
    Tested with build-many-glibcs.py for hppa-linux-gnu (Linux 6.2
    headers).
