base: don't specify Debian version in image name.

We have no intention of maintaining images with more than one Debian
version, and having the Debian version in the name simply makes version
updates more complicated.

This change isn't mentioned in the changelog because it's transparent to
users, who should be using the provided Dockerfile.
