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
```

With the introduction of the `bootloader` option, grub2 legacy
installation setting changed. Before, grub2 legacy installation
was dependent on the partition scheme, i.e. only when dos/mbr
layout was used grub2 got installed. After the change the default
is to install it unless `bootloader.type" is explicitly set, even
if the partition layout is GPT. But a legacy grub2 installation
on GPT requires a BIOS boot partition, so the new default is not
right for the case of pure (non-hyrid) UEFI images.
Therefore revert to the old behavior of only defaulting to grub2
legacy if the option is not explicitly set *and* the partition
layout is "dos"/"mbr".
Adapt the f30-qcow2-gpt sample, which is non-uefi grub2 legacy
but with GPT and a bios boot partition, to explicitly request
the grub2 bootloader.
