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.

Strongly inspired by the forgejo counterpart[1], for the following
reasons:
* The feature is broken with the current module and crashes on
authentication with the following stacktrace (with a PAM service
`gitea` added):

It only worked after turning off multiple sandbox settings and adding
`shadow` as supplementary group to `gitea.service`.
I'm not willing to maintain additional multiple sandbox settings for
different features, especially given that it was probably not used for
quite a long time:
* There was no PR or bugreport about sandboxing issues related to
PAM.
* Ever since the module exists, it used the user `gitea`, i.e. it had
never read-access to `/etc/shadow`.
* Upstream has it disabled by default[2].
If somebody really needs it, it can still be brought back by an overlay
updating `tags` accordingly and modifying the systemd service config.
