[PATCH v2 3/3] populate_sdk_ext.bbclass: Add SDK_RECRDEP_TASKS variable

[Randy Witt <randy.e.witt@linux.intel.com>]

Currently there isn't a way for the extensible sdk to know all the tasks
that will need sstate for an image. This is because a layer can add it's
on custom tasks that are required for an image to be generated.

The extensible sdk solved this for poky by using recrdeptask and
specifying the tasks known to be required for the image as well as for
building new recipes.

So the SDK_RECRDEP_TASKS variable allows a user to specify additional
tasks that need to be pulled in.
