This PR fixes a bug where `.ir` files lacked `modPkgExt` entries, causing incorrect module initialization function names when using `--load-dynlib` with the module system. When a transitive non-public import's data came from the `.ir` file instead of `.olean`, `getModulePackageByIdx?` returned `none`, producing wrong symbol names (e.g., `initialize_Batteries_Data_UInt` instead of `initialize_batteries_Batteries_Data_UInt`), leading to `dlsym` failures and double-registration errors.
