Flakeify home config
Use nix flakes instead of niv for pinning dependency channels. First step towards merging my "nixos-system" and "nixos-home" configs into a single trivially reproducible flake setup. Apply home config via: > nix build .#homeManagerConfigurations.common.activationPackage --impure > ./result/activate
