[docker] Use a multi-stage build for base-cipd

This saves ~300MB by stripping out the packages/files needed by intermediate
stages. Unfortunately, it's still around 400MB, but most of that is the CIPD
packages themselves. I think the best way forward is to have our apps
explicitly request the packages they need, rather than use a single base image
containing all possible packages. I've organized the Dockerfile so that the
"cipd" stage could act as the base for those specialized images.
