reshuffle Docker-related files

* The root docker-compose.yml was not used anywhere but the tests, so its
  contents was moved there.
* Some more refactoring and shortening of paths in t/i/docker.
* Removed .dockerignore files - I don't think they're needed, since I
  always use explicit COPY instructions with paths, etc., but I may as
  well be quite wrong on this one.
* Removed examples/docker/ - don't think this one was used at all?
