Subject: [PATCH] flake.nix: passthru machine `config`, `pkgs` and
 `config.system.build`

This shortens down the path needed to build both overlayed packages and
all the other machine derivations. Here are some examples:

```
nix build .#machine.etc
nix build '.#machine.units."nginx.service".unit'
nix build .#machine.pkgs.overlayed-package
nix build .#machine.config.services.nginx.package
```
