Some applications, like Qt's Vulkan demos, require the libvulkan.so
devlink to point at a valid Vulkan ICD loader. OE-Core has one that we
use so let's just use the alternative hooks to make sure that devlink
gets created without stomping on anything else.

To be dropped if upstream adopts something like this.
