Shareable Vulkan image allocation on Linux relies on the dma-buf interface, which is a Linux-specific thing. Therefore, we should only be compiling it (and any code that uses it) on Linux. This change adds preprocessor guards to do that. Enabling similar functionality on other operating systems will need to leverage analogous interfaces on those platforms, e.g. win32 handles on Windows. All Vulkan image code will now be guarded by the USE_VULKAN_IMAGES preprocessor definition, currently enabled on Linux if Vulkan is available. Additionally, we shuffle around some code in OpenGLContext.cpp to simplify the preprocessor conditionals.
