Subject: [PATCH] flake.nix: pkgs.system -> pkgs.stdenv.hostPlatform.system

`pkgs.system` is now an [alias][1] to `pkgs.stdenv.hostPlatform.system`.

After this it's possible to set `config.allowAliases = false` for nixpkgs:

```
nixOnDroidConfigurations.default = nix-on-droid.lib.nixOnDroidConfiguration {
  pkgs = import nixpkgs { config.allowAliases = false; system = "aarch64-linux"; };
  modules = [ ./nix-on-droid.nix ];
};
```
