camerabin: update preview buffer pushing

Browse source 
need to pass a GstSample to the utilitary preview buffer post functions
as a GstBuffer doesn't have caps anymore. The GstSample has the GstCaps
and it is used to inform the preview's pipeline about the format of the
input, before it gets converted to the user's requested output format.
