[gnome-system-monitor] dialog: use short process name instead of full

    dialog: use short process name instead of full
    
    When there is a long process name, the name of the
    process in the kill dialog is show in full. This is a problem
    because long process names (such as google chrome) cause the dialog
    to extend all the way across the room.
    
    This patch fixes that by just displaying the short process name
    without the command line parameters.
