    file-operations: use the right prototype for empty trash callback
    
    When unmounting, we might first prompt whether the trash should be
    emptied or not on the target volume. If we do so, make sure the callback
    from the empty trash job has the right prototype, to avoid crashing
    later trying to interpret a gboolean as a pointer to a data structure.
