nixos/kubernetes: bootstrap docker without networking

Browse source 
Before flannel is ready there is a brief time where docker will be
running with a default docker0 bridge. If kubernetes happens to spawn
containers before flannel is ready, docker can't be restarted when
flannel is ready because some containers are still running on the
docker0 bridge with potentially different network addresses.

Environment variables in `EnvironmentFile` override those defined via
`Environment` in the systemd service config.
