CI: containerize the CI

Reuse the templates from wayland/ci-templates:
whenever DEBIAN_TAG is changed, this will rebuild a new container.

This adds two things:
- better reliability (we do not randomly pull packages whenever the CI
  runs and we can reproduce with this particular environment)
- faster builds, as we do not need to pull the universe at each run
