    elf: Remove __glibc_likely from _dl_sort_maps
    
    _dl_sort_maps is only called during shared object loading and
    unloading, not on any hot path. The branch predictor hint has no
    measurable benefit, and removing it simplifies the code and avoids
    future maintenance when the default algorithm changes.
