Have GST_V4L2_IO_AUTO select GST_V4L2_IO_DMABUF.

Standard is for io-mode=auto to mean io-mode=mmap. dmabuf has
fast paths in kmssink, glupload and others.

This change is equivalent
gst-launch-1.0 v4l2src io-mode=dmabuf
without the need to set the property as the the default is auto
and auto is now dmabuf for capture.
