Subject: [PATCH] nix-darwin,nixos: add osConfig module argument (#2302)

Having either argument defined based on the OS is a problem when
trying to write generic Nix code.

The current workaround is to use accept both and specify a default
value for each argument:

```
{ config, lib, nixosConfig ? {}, darwinConfig ? {}, ... }:

let
  osConfig = nixosConfig // darwinConfig;
in
{
  # Do something with `osConfig`
}
```

With this commit, it becomes possible to do the following:

```
{ config, lib, osConfig, ... }:

{
  # Do something with `osConfig`
}
```
