gfxstream: kumquat: opaque fd or dmabuf, not both

Browse source 
So Mesa drivers actually don't like both:

src/vulkan/runtime/vk_device_memory.c:

"""
 case VK_STRUCTURE_TYPE_IMPORT_MEMORY_FD_INFO_KHR: {
   const VkImportMemoryFdInfoKHR *fd_info = (void *)ext;
     if (fd_info->handleType) {
       assert(fd_info->handleType == VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT ||
              fd_info->handleType == VK_EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT);
"""
