    universal-access: Remove redundant label-for relations
    
    The appropriate relation is already set with the mnemonic_widget property.
    
    In particular, this also fixes an issue where a screenreader would
    emit "Crosshairs" every time a new tab was entered in the Zoom dialog
    because of some incorrect labelled-by relations.
