This change verifies that `docker buildx` is available and then uses that
for building the images. For that we apparently need the magic line at
the top of the `Dockerfile`s and set the environment variable
`DOCKER_BUILDKIT`. This solves a problem building docker images on
Linux with an older Docker version where the heredocs didn't work.
