When VK_USE_PLATFORM_XLIB_XRANDR_EXT is defined, vulkan.h includes X11/extensions/Xrandr.h for the RROutput typedef which is used in the vkGetRandROutputDisplayEXT interface. Make sure we have the required header by checking during the build, and also set CFLAGS to point at the right directory. We don't need to link against the library as we don't use any functions from there, so don't add the _LIBS value in the autotools build.
