Subject: [PATCH] fix(iso): disable broken zfs in the live installer

The installation-CD profile enables zfs so you can install onto it, but
the pinned nixpkgs ships a broken zfs-kernel that fails to evaluate,
breaking `nix flake check` and ISO builds. Force-disable zfs in the ISO
(a desktop installer doesn't need ZFS-root); use the official NixOS ISO
for ZFS installs.
