arm-autonomy/xenguest: Generate xenguest.env containing variable values

Browse Source 
Added task "do_deploy_xenguestenv" to xenguest_image.bbclass which creates
intermediary files for each recipe that inherits xenguest_image. These files
are merged into the main xenguest.env file in DEPLOY_DIR_IMAGE by the task
"do_merge_xenguestenv" in image_types_xenguest.bbclass, which has a dependency
on all do_deploy_xenguestenv in recipes it depends on.

Variables to write to the file are listed in XENGUEST_IMAGE_VARS, and any
extra variables in child recipes should be added to XENGUEST_IMAGE_VARS_EXTRA

xenguest-image had to be renamed xenguest_image to use EXPORT, since dash is
illegal in bash function names.
