[Nix-dev] Patch: Downgrade NVidia Driver

[james.cook at utoronto.ca]

Hi nixpkgs patch-appliers,

    It looks like NVidia has taken down their latest UNIX drivers due
to a fan speed issue.  They've reverted from 195.36.08 to 190.53, so the
current NVidia expression fails with an HTTP 404.

    I've attached a patch for nixpkgs which I have tested on x86_64.
For x86 I downloaded the driver in order to update the sha256 hash, but
I did not test it.

Cheers!
  James
