Remove koji-osbuild.spec.in and the bits in meson.build that generate
the final spec file out of it. Pull in the changelog from how Ondřej
Budai does it in osbuild-composer, because it's adorable.
When releasing, the version now has to be bumped in the spec file.
This is to make it consistent with other osbuild projects, and to
simplify reverse dependency testing.
The CI is in two stages, for each supported distro.
First the RPMs are generated from the spec file in the repo for the
given distro and architecture.
Once all the RPM builds have succeeded successfully, a test machine is
provisioned with osbulid-composer installed, and koji API enabled.
The repository containing the RPMs of the code being tested is also
enabled on the test machine, and the cli client is installed.
Finally, the test/integration.sh script is executed, which currently
does nothing.
