    pango-ot-info: Fix an uninitialized value
    
    We never assign a value to l_index. Also, we pass on language_index to
    hb_ot_layout_script_select_language, even though the last parameter of
    that function is not nullable, while our language_index parameter is.
    
    Fix this to pass &l_index to hb_ot_layout_script_select_language, which
    is what I believe should happen.
