- fixed saved game thumbnails generation with Vulkan renderer

GZDoom aborts with 'Failed to submit command buffer' error on saving a game when open source Intel Vulkan driver (part of Mesa 3D package) is used on Linux
This driver generates VK_DEVICE_LOST error when vkWaitForFences() is called with zero fence count. It must be greater than zero according to Vulkan spec
