Change build process to include apt package lists
To help trigger rebuilds of downstream docker images when security, etc updates are available include the apt list files used to build the image.
The idea is to:
- Allow a tool like renovate to trigger pinned sha updates in Dockerfiles since the image will now always change
- Fix what version of packages are used based on what package lists files are present.
The package lists are pulled out to their own layer to avoid re-uploading the base image whenever an unrelated package changes.
