In general, the rules aren't listing the
^zink-radv-.*-valve jobs when they are in a namespace outside
mesa. It means when we attempt to do an uprev of piglit in mesa, those jobs will not be in the testing pipeline to know if the expectations would change. And later, if they need an expectations update, the merge request created by @gfx-ci-bot will fail (actually under development in gfx-ci/ci-uprev!39 (closed) but close to complete).
Introducing the condition of a change in the file where the piglit revision is set, we do the minimal change to allow these jobs to be present when preparing an uprev candidate.
