vulkan-samples: Disable PCH for reproducibility
We're still seeing reproducibility issues on the autobuilder with this recipe. I was able to make the output "match" by rebuilding the PCH and then rebuilding the binary objects, proving the PCH isn't deterministic. Disable PCH until we can get to the bottom of why that may be.
