license_image.bbclass: fix missing recipeinfo on self
Resolve a build bug where image recipes with a do_deploy task will fail.
If the image recipe inheriting license_image.bbclass has a deploy task, then
the function get_deployed_dependencies will add itself to the list of recipes
to get license information for.
However, image recipes don't generally deploy license info so this results in
an error.
File: '/nvme/poky/meta/classes/license_image.bbclass', lineno: 192, function: license_deployed_manifest
...
Exception: FileNotFoundError: [Errno 2] No such file or directory: '/nvme/poky/build/tmp/deploy/licenses/core-image-minimal/recipeinfo'
Add a corner case to exclude the originating image recipe from the list of
dependencies to check.
