Vulkan: Work around false positive on 64-bit Linux w/ 32-bit ICDs

In the vast majority of cases, this will be a false positive error
thrown by Vulkan-Loader when a Linux system has Vulkan ICDs for both
32-bit and 64-bit. The error is of the form:
```
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
```

The loader dlopen's the 32-bit ICDs first, raises this error, and then
happily goes on to try and use the 64-bit ICDs.

Upstream report: https://github.com/KhronosGroup/Vulkan-Loader/issues/262

Fixes #36185.
