Prevent electron-builder from adding native modules to asar on macOS (#4169)

Having native node modules packaged into the asar archive results in
them being unpacked and executed by electron when required by the app.
When macOS executes the unpacked native modules, it first sends requests
to Apple, and when the response is received or when the request times
out the module is loaded.
