[PATCH v2 1/5] CI: create own base buildah image instead of wayland's

[Andrzej Hajda <andrzej.hajda@intel.com>]

To allow to bump debian and fedora versions for build testing we need
reliable base container. Containers provided by
registry.freedesktop.org/wayland/ci-templates/buildah are quite old and
have multiple issues when used with newer OS versions.
Instead of relying on them or some other random registry let's take
bare buildah from reliable source and add required tools to it.
Base image will be built only if Dockerfile.build-buildah
is changed. Alternatively building can be enforced from gitlab:
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/pipelines.
