    pathbar: Drop gtk_widget_{g,s}et_clip()
    
    It's gone in GTK4 and removing this doesn't seem to cause any visual or
    behavorial change at the moment.
    
    Originally it was a workaround to some visual problem with button
    shadows. Our pathbar buttons don't have shadows nowadays, and even if
    testing with added shadows, there is no apparent issue nowadays.
    
    Rebased and ammended by António Fernandes <antoniof gnome org>
