Cleaned up a bit VideoCapture.java

Removed unused implements OnFrameAvailableListener
and empty overriden method.
Reduced scope of try-catch for setPreviewTexture IOException.

(Rest remains the same although diff is a bit confused).

Also removed unused |mColorPlane|.

Tested via local execution of getUserMedia to <video> tag,
