CI: Updated gitlab-ci and switched to new recipe name

The workflow for the integration of the gitlab-ci submodule has changed.
Updated the gitlab-ci yaml file to use the new workflow and also updated
the CI to the current revision.

Note: The name of linux-guf was changed to linux-seconorth for the 5.15
kernel.
