The mirror used in f30-ppc64le example did contain the RPM packages but
there were two issues
* f32 is not in development any more
* ppc64le is available as a secondary arch
The patch also renames the file as it contains packages for fedora 32.
This converts all fedora links in our samples to `mirrors.kernel.org`.
This mirror works best from around the world, so lets avoid the wild
mix of local mirrors and instead use kernel.org.
This mirror is also well-managed and properly funded, so we should not
run into too many problems with it.
As long as this matches the build environment, this does not make
a differenece, but let us not depend on this.
This will be useful when automatically transforming dnf to rpm
pipelines, as the platform_module_id is needed as input to
osbuild-composer's dnf-json tool.
Performed using this script:
```
cat $1 | jq '(.stages[]? | select(.name == "org.osbuild.dnf") | .options.module_platform_id) |= . + "platform:f30"' | sponge $1
cat $1 | jq '(.build.pipeline.stages[]? | select(.name == "org.osbuild.dnf") | .options.module_platform_id) |= . + "platform:f30"' | sponge $1
```

Include a example of a ppc64le (open firmware) pipeline based on
f30-s390x. It includes changes to the grub2 stage (selecting the
platform), the partition table contains the PReP partition needed
to store the grub2 core image.
