taalo-build: Rewrite as wrapper and move to pkgs
We no longer use the legacy SSH store protocol for taalo but the new ssh-ng protocol, which makes the implementation of taalo-build a LOT less clunky. It also didn't make sense to have this as a NixOS module when we after all just emit a static store path without any stuff depending on configuration options. The new implementation basically just wraps nix-build and nix-store -r along with the right NIX_REMOTE variable. With Nix 1.2 this can also be done with the new "nix build" command using the --store option, but unfortunately "nix build" doesn't yet have the same functionality as nix-build.
