vulkan/device_select: Stop using device properties 2.

We have to choose between:
1) Stop handling two identical GPUs
2) Stop having crashes with other layers active.
3) Fix the Vulkan Loader.

Since nobody seems to want to spend enough effort to do 3 the
effective choice is between 1 and 2. This is choosing 2, as
two identical GPUs is pretty uncommon since crossfire doesn't
work on Linux anyway.

(And it would only work sporadically as the game needs to enable the
 extension)
