Draft: Trim down the QEMU build
Refs #88
Trying to slim down our deployed software.
This MR builds on a suggestion by @jcalderone in #88. I don't think I am doing it right though, since the reported difference is minimal:
$ nix --extra-experimental-features nix-command store diff-closures result-before/ result-after/
initrd-linux: +13.1 KiB
