Update vmeta to use the dma_buf handling now provided by libbmm v2.
This permits more flexible buffer management, as the buffers can now
be passed via a standardized mechanism to other subsystems (such as
DRM), and image data to be encoded can be accepted directly from
other subsystems without needing to be copied.
