[PATCH vkd3d] configure: Allow specifying the Vulkan library path with VULKAN_LIBS.

[Zebediah Figura]

Do not define it for the vkd3d build, but restore support for overriding it as a

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
