circleci: switch to using the new docker images

In order to improve build time for the case where the docker image is
not cached on the current container we split the docker image into
multiple smaller ones.

Also, the images are now generated from the LKL docker hub
organization (https://hub.docker.com/r/lkldocker/) and the docker
files are stored in a separate gihub repo in the LKL github
organization (https://github.com/lkl).
