media: uvcvideo: Enable VB2_DMABUF for metadata stream

The UVC driver has two video streams, one for the frames and another one
for the metadata. Both streams share most of the codebase, but only the
data stream declares support for DMABUF transfer mode.

I have tried the DMABUF transfer mode with CONFIG_DMABUF_HEAPS_SYSTEM
and the frames looked correct.

This patch announces the support for DMABUF for the metadata stream.
This is useful for apps/HALs that only want to support DMABUF.
