console.useXkbConfig and boot.initrd.systemd.enable are set distro-wide
(lib.mkDefault true in modules/nixos/default.nix, since the LUKS-keymap
fix), so the installer rewriting them in the generated system.nix was
redundant. Drop them there and from the offline-pin test fixture in
flake.nix — the nomarchy module still defaults them on, so the closure
(and the pin set) is unchanged; verified the values still resolve true
and `nix flake check` passes. Only the machine-specific xkb layout is
written now. Adjusts the README keyboard-option wording to match.
