vulkan/overlay: Add a workaround semaphore for application presenting without one

When an application calls vkQueuePresent() on a different queue than
the one we run our drawing on and it doesn't give a semaphore to wait
on, let's insert our own semaphore so that we don't race the
application's drawing.
