docker: make docker-init a runtime dependency by default

If docker run --init is used docker expects docker-init to be
present, if not Docker fails to start the container with the
following error:
  docker: Error response from daemon: exec: "docker-init": executable file not found in $PATH.

However, docker-init does not get deployed by default since commit
d19fda374317 ("docker: consolidate common depends/options"). Readd
docker-init through a PACKAGECONFIG RDEPENDS to make sure it gets
deployed by default again.
