arm-autonomy: Create xenguest-image-extra class

Browse Source 
Add class xenguest-image-extra to be used by recipes which wants to add
elements to the generated xenguest image.
The recipes using this call must inherit the deploy class and declare a
deploy task that will be extended by the class. The variables
XENGUEST_EXTRA_* documented in the class can be used to define what
should be used to extend the xenguest image.
