vulkan: Add recipe for Vulkan common loader

Add a recipe for vulkan loader library and the vulkaninfo binary.

Vulkan can be built to support X11 or wayland or both. There is
currently no support for building tests, validation layers or even
the demos as that would require a bunch of otherwise unnecessary
dependencies.

Fix the build on musl by defaulting to getenv() if secure_getenv()
is not available.

+    demos: Don't build tri or cube
+    
+    There are more interesting demos, all we really want here is vulkaninfo.
+    This helps because we don't need to pre-build glslang/llvm/lunarglass
+    just to get the loader and layers.
