hashcat: add CUDA support (#240735)

Previously, hashcat was unable to use CUDA at runtime, and would warn:

> Failed to initialize the NVIDIA main driver CUDA runtime library.
> Failed to initialize NVIDIA RTC library.
> * Device #1: CUDA SDK Toolkit not installed or incorrectly installed.
>              CUDA SDK Toolkit required for proper device support and utilization.
>              Falling back to OpenCL runtime.

This remedies that, at least on NixOS.
