scripts/ci: update gitlab-runner playbook to use latest runner

We were using quite and old runner on our machines and running into
issues with stalling jobs. Gitlab in the meantime now reliably provide
the latest packaged versions of the runner under a stable URL. This
update:

- creates a per-arch subdir for builds
- switches from binary tarballs to deb packages
- re-uses the same binary for the secondary runner
- updates distro check for second to 22.04

Note this script isn't fully idempotent as we end up accumulating
runners especially during testing. However we also want to be able to
run twice with different GitLab keys (e.g. project and personal) so I
think we just have to be mindful of that during testing.

Jobs based on custom runners: docs and gitlab-runner setup playbook

To have the jobs dispatched to custom runners, gitlab-runner must
be installed, active as a service and properly configured. The
variables file and playbook introduced here should help with those
steps.

The playbook introduced here covers the Linux distributions and
has been primarily tested on OS/machines that the QEMU project
has available to act as runners, namely:

* Ubuntu 20.04 on aarch64
* Ubuntu 18.04 on s390x

But, it should work on all other Linux distributions. Earlier
versions were tested on FreeBSD too, so chances of success are
high.
