e2e: use docker.io/library as prefix for official images

Docker Hub offers a way to pull official images without any project
prefix, like "docker.io/vault:latest". This does a redirect to the
images located under "docker.io/library".

By using the full qualified image name, a redirect gets removed while
pulling the images. This reduces the likelyhood of hittin Docker Hub
pull rate-limits.
