chore: format everything

This implicates a change from nixpkgs-fmt to nixfmt. Nixfmt will become
the new standard on nix formatting, sanctioned by the nixpkgs. To verify
that these changes are purely in whitespace, but not semantic:

git diff --ignore-all-space -w HEAD^!

That will only show newline changes, make the diffing somewhat easier.
