Justin !andTom Hubrecht 32d7c02b96 nixpkgs: bump to 25.11
This bump nixpkgs input to 25.11 and fix the two warnings that were
coming with the update:

1. `pkgs.system` => `pkgs.stdenv.hostPlatform.system`
2. `runCommandNoCC` => `runCommand`

also:

1. remove cppnix 2.3 compat tests (cppnix 2.3 is officially dead now)
2. remove lowdown 1.3 compat tests (nixpkgs no longer carries it)
