gitlab CI: switch to using ci-templates

ci-templates encourages building specific containers that can be re-used:
- containers are re-used across pipelines, producing consistent results
- containers are re-used by contributors since they will use the upstream
  containers for their MR, thus guaranteeing the same results.

Containers are automatically rebuild whenever the respective
FDO_DISTRIBUTION_TAG changes. This is particularly interesting now that
Docker Hub will introduce pull limits.

This CI script consists of a config file and a jinja2 template, simply
running 'ci-fairy generate-template' produces the .gitlab-ci.yml.
ci-fairy is part of the freedesktop.org ci-templates and can be pip
installed, see the check-ci-script job.

Functional changes to the previous script:
- new job: check-ci-script, verifies that our gitlab-ci.yml is the one
  generated by the sources
- Added distributions:
  - Fedora 33
- The actual work is now down by a set of scripts in .gitlab-ci/,
  specifically:
  - .gitlab-ci/build.sh is the previous do_build job
  - .gitlab-ci/{fedora|debian}-install.sh are the previous {fedora|debian}_install jobs
  symlinks are in place for centos and ubuntu

Why the scripts instead of steps in the CI? Easer to reading and
reproduce. With the containers being static, it's easy to pull one
locally and re-run the CI job to reproduce an issue. Having everything in a
single script makes that trivial.
