gitlab-ci: Add a shader-db run using v3d on drm-shim.

This provides significant compiler coverage during CI at a fairly low
cost in CPU time (~17s per thread for 4 threads on
gst-gitlab-htz-runner3).

I'm leaving wget in the docker image, as once this is in master I'm
planning on having an automatic shader-db comparison between master
and the branch included in the artifacts.  I also haven't done
freedreno yet, because it has some races when run in multithreaded
mode that I'm still tracking down.
