camerabin2 remove redundant viewfinder-colorspace and viewfinder-scale

camrabin2 connects a viewfinderbin on "vfsrc". viewfinderbin is made of:
   vfbin-csp ! vfbin-videoscale ! videosink.

we should either remove csp/videoscale from wrappercamerabinsrc (as
done in this patch) or we should get rid of viewfinderbin altogether.
