WIP: vulkan: Update to sdk-1.1.106.0

Note the tag to use is the sdk-* one, from projects README:

Marked version releases have undergone thorough testing but do not
imply the same quality level as SDK tags

Also, hardcode the haeders location as according to upstream (https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/729) the vulkan-layer header should be installed to /usr/include/vulkan.

The current install location will break the build of the new mesa vulkan-overlay.
