[gnome-shell] statusMenu: change how we stop the system

[Ray Strode <halfline src gnome org>]

commit 26f4e44d6c78af77343347e8dba3e36eddcc6a63

    statusMenu: change how we stop the system
    
    This updates the way we stop the system to
    somewhat match the designs here:
    
    https://live.gnome.org/GnomeShell/Design/Whiteboards/SystemStopRestart
    
    We suspend by default unless suspend is unavailable, and offer shutdown
    as a choice by hold down the alt key.
