move Dockerfile back to root. DockerHub can't handle it elsewhere.

It looks like DockerHub's automated builds only have access to the
subtree of the source checkout at+below the Dockerfile. Putting the
Dockerfile in misc/build_helpers/ meant that the build process only had
access to misc/build_helpers/, not the full source tree.
