checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
Since virtio-gpu context types are now in upstream kernels, it is now
possible to use Sommelier without patching it or using custom kernels,
so I think it's finally suitable for inclusion in Nixpkgs.
I'm using the same versioning scheme I made up for crosvm here.
Figuring out the version is handled by the update script, which I
adapted from the crosvm one. Sadly there's too many differences
between them to easily merge them into one, so reducing duplication
between them is left as further work.
