Debian 32 bit dependencies for nvidia gpus not listed

[Simon-L]

These 32 bit libraries were needed for the leagueoflegends script (reimer's wine-lol) to work on Nvidia gpus on Debian testing:
# apt install libnvidia-glvkspirv:i386 libglx-nvidia0:i386
I suggest to confirm this and then add these to the readme.

This project and the readme are focused on arch, I just wish that distros were able to agree on more standard package names. From a quick search it seems lib32-nvidia-utils is the package that contains the missing libs, although it's weird that it contains everything ?!?

Describe the issue

For some setup (laptop with integrated and dedicated gpu in my case), the VK_ICD_FILENAMES environment variable is also needed so that the correct GPU is used. Setting that variable to the correct nvidia file and inspecting Vulkan drivers debug messages showed that these libraries were missing. LoL would otherwise only run using the testing vulkan lavapipe backend.

Steps to reproduce

Debian users with Nvidia gpus, see if you het the same error in vulkaninfo output.
Also try apt-cache policy libglx-nvidia0:i386 to check if it's already installed.

Thanks for letting me know the package names! Unfortunately I don't have Debian machines to confirm it, and I don't know the required package names for other distributions either (especially graphics related packages), so I'm unable to list all dependencies for all distributions. I will just add a paragraph in README explaining the situation with those two as an example. And hope someone will contribute by sharing the package names for other distribution+graphic card configurations.

Also, because I don't know if Debian/Ubuntu has meta packages for those Vulkan drivers, I'd rather not add specific drivers as hard dependencies in the deb package. Otherwise I'd be happy to.

As for setting VK_ICD_FILENAMES, I opened up a new issue tracking the enhancement #42, although I won't have time to implement that in the near future. So if anyone sees this, PRs are appreciated!
