Subject: 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
