[JENKINS-40723] Built Dockerfile images are never removed

When using a Dockerfile to set up the build environment (as added in JENKINS-39216), a docker image is built and tagged with the SHA1 hash of the Dockerfile. Nothing seems to remove this image once the build competes, so disk space on the docker node will eventually be exhausted.
