Ensure that only one Vulkan ICD manifest is present.

Install a single nvidia_icd.json file, regardless the target
architecture, to prevent having two ICD manifests present
when both x64 and i686 driver libraries are installed.
Having multiple Vulkan ICD manifest installed tricks the Vulkan
loader into thinking that there are two adapters installed.
