This includes support for KiCad 8 (see complete changelog
[here](https://github.com/yaqwsx/KiKit/releases/tag/v1.5.0)), which should unblock
https://github.com/NixOS/nixpkgs/pull/291134.
With this upgrade, a test started failing:
$ nix build .#kikit

This is failing in some pretty old kikit code, so I think this is just
failing due to kikit now having more complete code coverage. While
researching this, I discovered kikit's documentation about [optional
dependencies], which I suppose we don't have good support for right now.
Rather than invent a new option for that, I've opted to preserve the
existing behavior and just do the bare minimum to keep the build
passing.
