Gitlab pipeline for building core-image-minimal

Including these points (initially as separate commits):

* Try caching updater-repo in gitlab
* Only patch aktualizr recipe in CI if needed
* Run under user 4321 in bitbake docker image
* Add ability to supply METADIR to envsetup.sh

  So that we can bypass the "relative path from the script" trick that
  doesn't work with symlinks.
* Checkout the PR base branch
* do not run on pushes
* run on runners with "gitlab" tag
* Print all revisions after repo checkout on CI
* Pull CI image from the base branch instead of master
* More robust checkout in CI
* Only store updater-repo artifacts for one day
* Use "stretch" instead of "stable" for Debian release in Dockerfile
  (in fact, stable just changed to buster)
* Move UPDATER_REPO variable out of .gitlab-ci.yml
  To be defined in the project's settings
* Make docker CI stage buildable on shared runners
