use kernel's v4l webcam emulate driver "VIVID".
simple-dmabuf-ion,
for post ION allocated dmabuffer As NV12 format, post to video plane

simple-dmabuf-egl-yuv-on-osd,
for post gbm_bo_create allocated dmabuffer As NV12 format buffer,
weston get dmabuffer, but the gbm_bo_import will failed, so
force_renderer enabled and Posted into OSD plane.
