### Electron Forge version

7.4.0

### Electron version

v24.1.1

### Operating system

macOS 11.3.1

### Last known working Electron Forge version

### Expected behavior

Using `electron/universal` configured with `osxUniversal` in forge config, we expect all dependent modules will receive the correct `arch` and build themselves accordingly.

### Actual behavior

We are using `ffmpeg-static` in our Electron app, but when the universal build is created, only the arm64 ffmpeg binary exists. I have confirmed that the `ffmpeg-static` module can be rebuilt in CLI with an `arch` param (`npm rebuild --arch=x64 -f ffmpeg-static` and confirmed with `file node_modules/ffmpeg-static/ffmpeg`). In this case the correct binary is build/fetched. But when running the universal build with forge, only `os.arch()` seems to be respected, which in this case is an M1 machine.

It seems electron-forge isn't passing the correct arch to dependencies. If there were hooks in the universal build process, or some env vars set, I could manually rebuild this one ffmpeg module according to an arch. For example `ffmpeg-static` does obey `process.env.npm_config_arch`, so if I were able to set that in between the x64 and arm64 builds (or electron/universal did), the module would build the correct ffmpeg binary.

I have attempted using hooks in electron-forge to try and switch based on `arch`, but that value is always `universal`. Also, building the app on separate Intel and M1 machines does produce the appropriate ffmpeg binary.

### Steps to reproduce

Set up a project with `electron-forge` and `ffmpeg-static`, then attempt a universal Mac build.
