Fix python3-config --configdir
    
    00205-make-libpl-respect-lib64.patch only modified LIBPL in
    Makefile.pre.in which leads to an inconsistency in
    python3-config --configdir which uses the unmodified LIBPL (use
    /usr/lib instead of /usr/lib64).
    
    00102-lib64.patch now updates LIBPL in configure.ac instead, as it is
    done in Python 3.8 patch. Remove
    00205-make-libpl-respect-lib64.patch.
