Update NIX package

[Rucadi]

I'm just playing around with cosmopolitan, for that, one of the easiest ways for me to install any software is to use nix.

However, the latest supported version on nixpkgs seems quite old
https://search.nixos.org/packages?channel=unstable&show=cosmocc

Being in the moment of writing this the 2.2 version.

I would appreciate if this package is given some love and updated to the latest version :)

I think this was hard because of cosmocc's relative metacircularity. See discussion at #1117.

I guess “someone” (hi, up for some spelunking?) needs to either package the binary blob for cosmocc (the “extra files” being downloaded above), or what amounts to the same thing, write a rule to bootstrap cosmocc from said binary blob.

This is not currently planned; further discussion on redbean discord in #nix.
