QVulkanWindow: fix fatal warning on Clang 4

qtbase/src/gui/vulkan/qvulkanwindow.cpp:1882:42: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
        VkClearColorValue clearColor = { 0.0f, 0.0f, 0.0f, 1.0f };
                                         ^~~~~~~~~~~~~~~~~~~~~~
                                         {                     }
1 error generated.

VkClearColorValue is a union, so it wants to be clear that we are
initializing only one of the union's members, apparently.
(Even though initing more than one wouldn't make sense.)
