swapchain: add a case for minImageCount in capabilities
When creating a swapchain around a single-buffered SurfaceTexture, the
VkSurfaceCapabilitiesKHR structure obtained was giving a minImageCount
of 2 and a maxImageCount of 1, which should both be 1 in this case.
Test: create a swapchain around a single-buffered SurfaceTexture should
give back 1 as minImageCount from VkSurfaceCapabilitiesKHR
