default.nix: say which old Nix version is being used 

We are hitting a long tail of problems at work related to old nix-direnv
sneaking old nix versions in that would be fixed by
https://github.com/nix-community/nix-direnv/pull/513, except that the
issue is that nix-direnv itself is too old.

It would at least be very helpful to print out *what* ancient nix
version is at fault.
