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
This changes the bootloader for iso generation from Grub to
syslinux. In addition this adds USB booting support, so that
"dd" can be used to burn the generated ISO to USB thumbdrives
instead of needing applications like UnetBootin.
