Allow v4l2src element to connected to vaapipostproc or vaapisink when "io-mode" is set to "dmabuf-import". In practice, this is a more likely operational mode with uvcvideo. Supporting v4lsrc with "io-mode" set to "dmabuf" could work, but with more demanding driver or kernel reqs. Note: with GStreamer 1.4, v4l2src (gst-plugins-good) needs to be built with --without-libv4l2. https://bugzilla.gnome.org/show_bug.cgi?id=743635
