Nicolas DufresneandLaurent Pinchart 632e0fc09f v4l2: Extend device caps with V4L2_CAP_STREAMING

This capability tells the application that mmap() is supported. GStreamer
would return an error saying there there is no input/output method supported
by this device otherwise. This was tested with:

LD_PRELOAD=$(pwd)/build/src/v4l2/v4l2-compat.so GST_DEBUG="v4l2*:7" gst-launch-1.0 v4l2src ! videoconvert ! autovideosink

With this patch, GStreamer will reach playing state. It then blocks waiting on
poll() which is not implemented yet on our side.
