docker: introduce -clie package

By the docker-packaging repository and https://docs.docker.com/engine/install/centos/#installation-methods
docker is packaged by most distros with a split between the engine and the CLI.

We do the same here, by introducing the -cli package

But to keep existing use cases working, we also create a RDEPENDS between the main
docker package (the engine) and the cli, so existing "docker" package installs will
continue to work the same way. To have separate and non-redepending packages created
set the DOCKER_UNIFIED_PACKAGE variable to False
