make-iso9660-image: produce stable GPT disk GUID

Browse Source 
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
