Sync2Test.SwapchainImage Release build segfaults on Ubuntu 24.04 AMD RX 6800 XT Wayland server

[lunarpapillo]

We're trying to upgrade our Ubuntu 24.04 test machines to use the Wayland display server instead of the older Xorg display server. https://github.com/LunarG/Projects/issues/956

Running Vulkan-ExtensionLayer commit v1.4.350-1-gf8568a6 with a Release64 build, running on an Ubuntu 24.04 host with an AMD RX 6800 XT GPU and running a Wayland display server, segfaults in Sync2Test.SwapchainImage: http://tcubuser.lunarg.localdomain:8080/view/Manual/job/manual-Vulkan-ExtensionLayer/69/console

Oddly, the exact same commit run with a Debug64 build passes: http://tcubuser.lunarg.localdomain:8080/view/Manual/job/manual-Vulkan-ExtensionLayer/70/console

@jeremyg-lunarg did the synchronization2 layer. I am assuming this is an issue in that layer based on the test name. @jeremyg-lunarg want to take a look?

[charles-lunarg]

I already took a look and identified that this repo does not use wayland in its test framework. Adding it fixes the segfault (though that was local testing, I will do a manual run to confirm).

Edit: the manual test run has passed, confirming the fix.
