Make it possible to not have to copy everything into container

We do not want to copy the whole project into the Docker
container due to 'go get' using GOPATH (which, by default,
is the project root) as mentioned in #33. We don't need
the vendor folder to pull this off, but it makes more
clear which pkgs are considered 'external'.
