[gnome-session] Make the fail whale a separate program

commit f2ae6ebe04f7fe89acbb76ff61acbb4ef0c5c5e2
Author: Matthias Clasen <mclasen redhat com>
Date:   Fri Nov 23 01:59:07 2012 -0500

    Make the fail whale a separate program
    
    This makes it easier to test, and makes gnome-session itself
    a bit smaller.
