CI: Hardcode the artifacts path in the generated job description

Some gitlab update(?) seem to have changed the behaviour in variable passing. In the scripts the variables are available but in the artifacts path does not resolve them any more. May be it has something to do with the introduction of the trigger:forward keyword.
