Replacing nixcfg with libkookierebuild

Generally, nixcfg grew out of a dotfiles repository, that happened to
also have some scripts in it. As more and more of the configuration
was replaced with nix specifics (home-manager, etc...), so did nixcfg
change over time (previously "stuff").

As part of this, kookiepkgs was introduced along-side nixcfg, to make
it easier to add custom things to nixpkgs-based systems
(NixOS). Additionally, the core system configuration was handled via
private infrastructure repositories, each specific to the machine in
question.

The problem with this approach is a lot of redundancy when building
non-userspace (read home-manager) systems and a lot of chaos with
having to cherry-pick commits from different branches to work with
nixpkgs trees in development.

Ultimately, keeping both new package definitions, patches and
configuration for the root system and userspace (home-manager) in the
same repository is a _much_ better approach to solving these issues.

And as such, libkookie was started: the general idea is that it
includes all nix expressions that are relevant to _any_ of my
computers. Under `roots`, a machine can have it's primary
configuration file which is built andcopied into the nix store, so
that nixpkgs can always point at the version a generation was built
with, not what is on disk).

Overlays contains everything that kookiepkgs used to, modules contains
both system-level modules (only required on NixOS), as well as
anything that is being built with home-manager. Modules are all kept
in the same tree, however some require system-level access while
others don't. There could be some kind of list to distinguish the two,
so that userspace-only systems can still take advantage of libkookie.
