Carnix: 0.6 -> 0.7

[P-E-Meunier]

Motivation for this change

Carnix 0.7 improves support for workspaces, environment variables, and introduces the external cargo command cargo generate-nixfile.

The src field for workspaces, in the generated code, is now split between an src field, pointing to the root of the workspace, and a member field, specifying the remainder of the path. This fixes issues with members pointing to each other, and to the root.

Also, environment variables generated by build scripts are now handled properly.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option build-use-sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.
