Now that all callbacks of the loose source operate on `struct odb_source_loose` directly we no longer have to reach into the "files" source at all. Drop this field and update `odb_source_loose_new()` to instead accept all parameters required to initialize itself. This ensures that the "loose" backend is a fully standalone source.
