ffeat(ops/nixos): Add a dummy to make depot available in modules r/853

Because modules are not called via the default depot setup (for now
...), this introduces a dummy module that stores the depot tree itself
in the module configurations.

This makes it possible to write modules that use packages from the
depot.
