[Buildroot] [PATCH v9 1/1] docker-engine: split docker-{cli, engine}, bump to v18.09.0

Docker upstream has split the Docker daemon and CLI into separate codebases:

 - github.com/docker/engine: daemon, "dockerd" binary
 - github.com/docker/cli: "docker" command line interface

This commit splits the docker-engine package into docker-engine and docker-cli.
Conveniently, the Docker project has begun maintaining two separate
release-tagged repositories for the CLI and daemon as of v18.06-ce-rc1. Previous
versions were tagged in a common "docker-ce" repository which makes compilation
awkward for Buildroot, especially due to some limitations in the new Go package
infrastructure.

Docker repositories "engine" and "cli" recently started tagging releases. Select
the latest stable release, v18.09.0.

The CLI is no longer automatically included with the engine. Users will need to
select BR2_PACKAGE_DOCKER_CLI to produce a both docker and dockerd target
binaries.

Docker CLI can be statically compiled. This enables usage of the system docker
client binary to access the parent daemon API from within containers, where
shared libraries are not available.
