This fixes how berry internalizes its own version. By default a static 0.1.7 is
and overriden if a `.git` folder does exist. In that case `git describe` is used
and the version parsed out of it.
This PR unconditionally patches the version in the configure file as that appears
to be easier and more idiomatic than a "fake git".
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.

Upstream XMonad was using our xmonad patch file for their flake build to
support our nixos module. This would of course break the build upstream
if the version we patched and their master branch diverged. We
[discussed] that it'd make sense to upstream the environment var code.
In the process it seemed sensible to rename the NIX_GHC variable as
well, since it isn't really Nix-specific – it's just a way to set the
GHC binary to execute. This change has been [implemented] upstream in an
unreleased version of xmonad now – meaning we'll be able to drop the
xmonad patch soon!
This also clarifies the situation in nixpkgs a bit: NIX_GHC is easy to
confuse with the environment variable used in the ghcWithPackages
wrapper where it is used to set an alternative prefix for a GHC-wrapper
for applications trying to discover it via e.g. ghc-paths. It is an
implementation detail in this context, as it is in the case of the
xmonad module. Since they are different implementations doing different
things, different names also make sense.
