Camilla Löwy 1d8d1ff3d0 Fix output for missing Vulkan surface extensions 
When the Vulkan loader is present but there are no required surface
extensions, as will for example happen with the Null platform, glfwinfo
caused an error in glfwGetPhysicalDevicePresentationSupport and produced
confusing output.
