fix(controller): remove patched docker

The original intention of this was to fix the deis-*-data containers from failing to come up due to an issue with upstream Docker (ref deis/docker@3d9cd1e). Unfortunately, whenever you reboot the machine, the bind-mount is reset, which makes the client incompatible with the server. We should wait until the next Docker release isin CoreOS before implementing data containers.

By proxy, this also means that `deis logs` will not work until we can come up with a solution.
