hwcontext_vulkan: add the mapped software frame as an upload dependency 
We do uploads asynchronously, and we map the software frames in
order to avoid 2-stage copying. However, whilst we added a dependency
upon the mapped buffers, we did not add the original frame backing
those buffers as a dependency.

This caused issues on RADV, particularly with RGB images.
