feat(tvix/cli): add benchmark for bf286a54bc

Browse source 
cl/7558 used this expression as a benchmark to justify the introduction
of LightSpan::Delayed:

  builtins.length (builtins.attrNames (import ${pkgs.path} {}))

Let's add it as a benchmark case so it can be referenced easily.

Benchmark: {"nixpkgs-attrnames":{"kbytes":"233824","system":"0.32","user":"2.02"}}
