    listbox: Fix keynav_failed() parameter in move_cursor()
    
    The 'direction' parameter to gtk_widget_keynav_failed() is based on
    gtk_list_box_move_cursor()'s 'count' parameter. However if the passed
    in movement is GTK_MOVEMENT_DISPLAY_LINES, 'count' is modified by
    the keynav handling and will always be 0. To avoid messing up the
    'direction' parameter, use a local variable for keynav handling and
    leave 'count' untouched.
