Fix idk package_docker_all CI job (#2196)

Before, we were building docker images for IDK for each of the four
linux/darwin amd64/arm64 platfrom/arch combinations, which didn't make
sense. If we want to later build docker images for linux/arm64, we can
add that later.

I also cleaned up the Dockerfile for IDK to minimize creation of excess
layers (by &&-ing RUN commands), and made apt quieter to cut back some
of the noise.
