By generating a version-5 GUID based on $out (which contains the derivation hash) and preventing isohybrid from overwriting the GPT table (which already is populated correctly by xorriso). Tested by: * booting from USB disk on a UEFI system * booting from USB disk on a non-UEFI system * booting from CD on a UEFI system * booting from CD on a non-UEFI system * booting from CD on an OSX system Also tested that "nix-build ./nixos/release-combined.nix -A nixos.iso_minimal.x86_64-linux -I nixpkgs=~/nixpkgs-r13y --check" now succeeds. Fixes #74047
