libcamera: v4l2_videodevice: Clarify setting of v4l2_buffer timestamp
Add a comment to clarify why we set v4l2_buffer timestamp while
queuing the buffer (VIDIOC_QBUF). The timstamps are required to
be supplied for memory-to-memory devices for output streams which
then are copied to capture stream buffers with the help of
V4L2_BUF_FLAG_TIMESTAMP_COPY (set by the driver).
