Unlike JS-only modules, native add-ons are always associated with a dynamic shared object from which they are loaded. Being able to retrieve its absolute path is important to native-only add-ons, i.e. add-ons that are not themselves being loaded from a JS-only module located in the same package as the native add-on itself. Currently, the file name is obtained at environment construction time from the JS `module.filename`. Nevertheless, the presence of `module` is not required, because the file name could also be passed in via a private property added onto `exports` from the `process.dlopen` binding. As an attempt at future-proofing, the file name is provided as a URL, i.e. prefixed with the `file://` protocol.
