Use `$(DOCKER_RUN)` for cli plugins build.
Use `$(DOCKER_RUN)` for cli plugins build.

Seems I rebased over b039db985a4b ("Make it possible to override the volume
mounts and shell for the dev container") at some point and failed to notice
that some of the variable names had changed.

In the meantime the underlying issue was fixed in #1698 but here we switch to
using `$(DOCKER_RUN)`. This means that these rules now use
`$(DOCKER_RUN_NAME_OPTION)` and thus obey the `$(DOCKER_CLI_CONTAINER_NAME)`
variable.
