dma-buf/dma-fence: remove unnecessary callbacks
The fence_value_str and timeline_value_str callbacks were just an
unnecessary abstraction in the SW sync implementation.
The only caller of those callbacks already knew that the fence in
questions is a timeline_fence. So print the values directly instead
of using a redirection.
Additional to that remove the implementations from virtgpu and vgem.
As far as I can see those were never used in the first place.
