Current, the `cabal2nix` derivation contains both the executable, and a wrapper
that adds `nix` and `nix-prefetch-scripts`, which are required for some
features.
However, when calling `callCabal2nix` to create a derivation from a cabal file
at evaluation time,
these features are not actually used, but the huge closure of
`nix-prefetch-scripts` (which includes multiple vcs, as well as python and perl)
still needs to be fetched.
This commit splits cabal2nix into a lightweight version that is a standalone
static binary (`cabal2nix-unwrapped`), and a wrapper that includes the proper
dependencies in the path for full usage of the command line
utility (`cabal2nix`).
This commit also switches to the default ghc, to reduce the likelyhood of
building a different ghc when calling `callCabal2nix`.
The `src.meta` attribute does not exist, and even if it did the derivation does
not have a `rec` to reference it. This appears to be breaking all ofBorg meta
evaluation checks:
```

This branch currently seems an almost adequate replacement for gtk2 claws-mail,
except that clicking links in the web view opens them in the email window even
when "open links with external browser" is enabled.

According to the Cargo documentation:
> The build script does not have access to the dependencies listed in
> the dependencies or dev-dependencies section (they’re not built
> yet!). Also, build dependencies are not available to the package
> itself unless also explicitly added in the [dependencies] table.

This change separates linkage of regular dependencies and build
dependencies.
extraModprobeConfig could be applied too late i.e. if the driver has been
loaded in initrd, while the harddrive is still encrypted.
Using a kernelParams works in all cases however.
This patch partially fixes#81985.
Cross-compiling rtl-sdr is possible using this patch.
Use nix build -f <nixpkgs-path> -A pkgsCross.raspberryPi.rtl-sdr to build rtl-sdr.
The error that occured when trying to do this before was as follows:
