lanzaboote-tool: Remove

The lanzaboote-tool doesn't really see much attention in nixpkgs. See
the hydra build failures:
https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.lanzaboote-tool.x86_64-linux
It doesn't make much sense in nixpkgs anyway. It's basically useless
without the stub and the nixos module, neither of which is
present. Users should migrate to the Nix expressions provided by [the
main lanzaboote repo](https://github.com/nix-community/lanzaboote).
