Android Video Capture: Using full class path for Camera+subclasses to avoid @deprecation warnings

Since @SuppressWarnings("deprecated") doesn't work for
import statements, the only option is to use the fully
qualified class path in every reference.

To be sure, two deprecation warnings still remain,
namely in the use of

public abstract class VideoCapture implements android.hardware.Camera.PreviewCallback {

That somehow is not covered by the suppression.
