Dockerfile: Make it easier to use ctr in shell container

Browse source 
Running `ctr` in `make shell` doesn't work by default - one has to
invoke it via `ctr --address /run/docker/containerd/containerd.sock -n
moby` or set the CONTAINERD_{ADDRESS,NAMESPACE} environment variables to
be able to just use `ctr`.

Considering ephemeral nature of these containers it's cumbersome to do
it every time manually - this commit sets the variables to the default
containerd socket address and makes it much easier to use ctr.
