Subject: [PATCH] lixPackageSets.nix-eval-jobs: add `nix` passthru attribute

nix-eval-jobs is intimately tied to a specific Nix/Lix release and the
Nix specific version includes a passthru attribute so downstream users
can easily refer to it.

Propagating the same pattern for the Lix version allows it to more
readily be used as a drop in replacement.
