Hi, this patch breaks the swupdate (:swu) image type in isar-cip-core.

While I was not able to locate the root cause, I checked that the
swupdate.inc correctly appends the needed dependencies to
IMAGER_BUILD_DEPS:swu. Also, I saw that the packages never appear in
do_image_tools[depends]. Where they get lost remains unclear.

To debug this, I recommend to just look at the dependency graph
(bitbake -g cip-core-image, grep task-depends.dot "...").

Best regards,
Felix
