Since the measured rootfs work has been merged to main, and then
brought in to the CCv0 via the weekly merge, we have introduced a few
regressions related to how we build it / use it.
This PR attempts to make sure the artefacts are properly built, using
GitHub Actions, so the feature can be used with the operator.
Fixes: #7235
