revise anaconda_install_done needles
    
    GTK+ 3.19.10(?) has changed things in current F24/Rawhide;
    weirdly, done-freetype262 seems to match sometimes but not
    always. Add a new needle from a current screenshot but keep
    freetype262 around for now just in case. Drop some variants
    that should never be needed any more, rename the original
    needle to -23 to mark that we're only keeping it around for
    the F23 two-week Atomic tests. For now keep french-cantarell20
    as the 'official' French needle, we'll see if it hits any
    failures when the tests are working a bit better.
