    status/system: Update text of orientation lock menu entry
    
    Since the orientation lock menu entry is a proper menu entry instead of
    a icon-only button now, we also show a description-text for that entry,
    so update this text depending on whether orientation is locked or not to
    better reflect what clicking the menu entry will do.
