nix upgrade-nix should be removed and users should simply re-run the installer to update on non-NixOS/nix-darwin

There are a few small changes to apply on top of CL2075, particularly in regards to doing "update" on Lix, but I think we can do some initial hacky version pretty much in that CL.

But before that, I'd like to discuss something. The CL uses nix-env CLI, which is infamously yucky. Here are a few concerns I have:

The patched code checks if CppNix is installed with nix-env --query --installed -A nix, but uninstalls it with nix-env --uninstall nix; --uninstall can't be used with -A, and -A is a pretty big difference. I don't think it actually matters here, but is there a cleaner way?
CppNix is upgraded to Lix in two commands: nix-env --uninstall nix, then nix-env -i <lix-from-tarball>. This is kinda ugly and creates an extra profile for no reason
Lix is distributed in the lix-installer tarball, so upgrade would require manually downloading a new tarball, which is yucky until #13 is fixed
We need to figure out lix-installer releng to push out newer versions with installation fixes, and ideally, teach lix-installer to update itself, to be more sure that it will work fine
