[Buildroot] [git commit branch/2018.02.x] docker-engine: add dependency on docker-proxy

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=16a52502ae9f327745d0fe65ab1b3d4f0bd6a6e5
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

docker-proxy is needed by docker-engine at runtime, and was
previously not included. This leads to the following error
when attempting to port-map ports to a container:

  $ docker run -p 8080:8080 nginx
  docker: Error response from daemon: driver failed programming external
  connectivity on endpoint:
  exec: "docker-proxy": executable file not found in $PATH.

Docker expects the docker-proxy binary to exist in the PATH.
