gnu: volk: Hard-code path of vulkan-loader for dynamic loading

Browse source 
Until now, we’d get:

  $ guix shell vulkan-tools -- vulkaninfo
  ERROR at /tmp/guix-build-vulkan-tools-1.3.280.0.drv-0/source/vulkaninfo/./vulkaninfo.h:412: Failed to initialize: Vulkan loader is not installed, not found, or failed to load.

This patch fixes it and potentially for other programs as well.

* gnu/packages/vulkan.scm (volk)[arguments]: use gexp.
<#:phases>: Patch dlopen with libvulkan.so.
[input]: Add vulkan-loader.
