Install both ramdisks in the ipa downloader

- Make the different ipa-ramdisk packages installable side by side
- Clean the ipa-downloader Dockerfile from what seems to be unneeded
- Get both images in
- Use zstd instead of xz for better speed
- Check sums before redoing certs integration
- Add value to metal3 chart to select between architectures
- Get the two ESP available as well
