    Add xdg-su program to gparted.desktop file (#699626)
    
    Add xdg-su to list of graphical switch-to-root programs to be
    considered for gparted.desktop file.
    
    The openSUSE GNU/Linux distribution includes the program xdg-su by
    default for graphically prompting for root privilege.
    
    This enhancement enables a user to compile and install gparted from
    source code on openSUSE and have the gparted menu entry graphically
    prompt for root privilege.
    
    Bug #699626 - Enable gparted.desktop to prompt for root on default
                  openSUSE installation
