    file-operations: Make "trash on unmount" dialog modal
    
    Actually set the parent window, instead of juggling with GdkScreen,
    which is going away with GdkScreen. Furthermore, parentless dialogs
    should not exist, HIG-wise.
    
    While we are at it, also remove gtk_window_set_skip_taskbar_hint()
    which is going away with GTK4 too.
