Retroarch AppImage does not start with video driver set to vulkan on Linux/mesa/RADV

Description

With video_driver = "vulkan" set Retroarch immediately crashes, it does not even start.

Vulkan works with literally everything else on my system.

Expected behavior

Retroarch starts.

Actual behavior

It crashes.

Steps to reproduce the bug

1. Be running a Linux system, possibly specific to AMD GPUs and mesa
2. Run the AppImage
3. Set video driver to vulkan
4. Try running Retroarch again

Reproduce the crash with the AppImage, Linux/Mesa/RADV environment, and video_driver = "vulkan". Start with the video_driver_init_internal() failure and the logged Vulkan instance-creation errors. Done means RetroArch starts successfully with the Vulkan video driver on the reported setup.
