nixpkgs: take Nixpkgs path from argument

This removes the dependency on the `nixpkgs` channel within the
modules for state version ≥ 20.09. The default Nixpkgs source starting
from this state version is the path of the `pkgs` argument used to
bootstrap the Home Manager modeuls.

This is a prerequisite for using Home Manager withing Nix flakes.

* The `nixpkgs` module no longer references `<nixpkgs>`. Before it would do so when building the `pkgs` module argument. Starting with state version 20.09, the `pkgs` argument is instead built from the same Nixpkgs that was used to initialize the Home Manager modules. This is useful, for example, when using Home Manager within a Nix Flake. If you want to keep using `<nixpkgs>` with state version ≥ 20.09 then add

[source,nix]
_module.args.pkgsPath = <nixpkgs>;

to your Home Manager configuration.
