The "legacy" option in stages/org.osbuild.grub2 defaults to True:
`legacy = options.get("legacy", True)`
If both legacy and uefi is enable, the stage will try to create a hybrid
image, but that fails for aarch64. This patch makes sure we use uefi
mode only which fixed this issue.
I tested the patch by hand together with the fix from this PR:
https://github.com/osbuild/osbuild/pull/308
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
```

Pipelines encode which source content they need in the form of
repository metadata checksums (or rpm checksums). In addition, they
encode where they fetch that source content from in the form of URLs.
This is overly specific and doesn't have to be in the pipeline's hash:
the checksum is enough to specify an image.
In practice, this precluded using alternative ways of getting at source
packages, such as local mirrors, which could speed up development.
Introduce a new osbuild API: sources. With it, a stage can query for a
way to fetch source content based on checksums.
The first such source is `org.osbuild.dnf`, which returns repository
configuration for a metadata checksum. Note that the dnf stage continues
to verify that the content it received matches the checksum it expects.
Sources are implemented as programs, living in a `sources` directory.
They are run on the host (i.e., uncontained) right now. Each source gets
passed options, which are taken from a new command line argument to
osbuild, and an array of checksums for which to return content.
This API is only available to stages right now.
Based on the UEFI sample (f30-base-uefi.json). NB: the inclusion
of the dracut-config-generic is needed to disable "host-only" for
dracut so the initramfs will include the virtio_blk block device
driver that is needed to mount the root file system when running
the image in qemu.
