license_image: Fix race

The current code pokes into do_deploy manifests from do_image_complete when the
do_image_complete task may or may not depend upon the do_deploy tasks in question.
Often it gets lucky, sometimes it results in build failures.

To fix this, split the functionality to its own task which can have the correct
task dependencies. This means the data in BB_TASKDEPDATA is definitive, the other
code can be dropped, as can the IMAGE_EXTRATYPES do_populate_lic dependencies
from image.bbclass.

This fixes bugs which show up as:
