26.05: source Lix from nixpkgs, fix disko btrfs label

Browse source 
nixos-26.05 removed lix_2_93, which the lix-module release-2.93 branch
hard-pins via lixFromNixpkgs (no 2.94 module release exists yet). Drop
the lix-module input and set nix.package = pkgs.lix, which is Lix 2.94.2
on 26.05 — so we stay on Lix, just sourced from nixpkgs.

Also: newer disko dropped the btrfs `label` option; pass -L nixos via
extraArgs instead so the impermanence rollback still finds the "nixos"
label.
