vulkan-validationlayers/xxhash.diff

Avoid the installation of a custom xxhash.h header. Since vk_*.h header files
still include xxhash.h (and now would source the system xxhash instead of the
bundled one), it makes sense to build ValidationLayers itself with the system
xxhash as well, so that the ABI matches.
