[pango/hyphen-crash] Drop some leftover code

[Matthias Clasen <matthiasc src gnome org>]

    Drop some leftover code
    
    In d6bc8daa6935b53c1, we added code to remove "hyphen runs".
    But we no longer create such runs, so this code is harmful
    and can cause crashes under certain circumstances.
    
    Closes: https://gitlab.gnome.org/GNOME/pango/issues/418
