ci: enable shader-db on lima
This adds literally a couple of seconds of runtime to this new shader-db job and FWIW it would have helped catch issues like #9687 (closed) #9688 (closed) #9689 (closed) that we entirely missed before (see https://gitlab.freedesktop.org/mesa/mesa/-/jobs/46264712#L4995 ). Those are already fixed with !24855 (merged) .
