Vulkan broken with Nvidia on unstable

[nyanloutre]

Describe the bug
Can't use Vulkan on the latest nixos-unstable channel.

To Reproduce
Steps to reproduce the behavior:

$ vulkaninfo 
ERROR: [Loader Message] Code 0 : libGLX_nvidia.so.0: cannot open shared object file: No such file or directory
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.
/build/source/vulkaninfo/vulkaninfo.c:923: failed with VK_ERROR_INCOMPATIBLE_DRIVER

Expected behavior
working Vulkan

Additional context
Strangely it's working with steam-run vulkaninfo (and Proton games running in steam are working)

LD_LIBRARY_PATH=/run/opengl-driver/lib vulkaninfo is also working

strace without steam-run:

#69037 might be related

This just might be the regression from patchelf if that's in unstable, vulkaninfo works fine for me.

[ambrop72]

I've submitted a fix in #69820.

Sorry about the comment, turns out I was just using a local nixpkgs where the issue was fixed already.
