Fix VBV macroblocking that comes up with the last Intra frame

This patch enables the VBV Lookahead computation of an I Slice to consider the
last MiniGop frames available in the lookahead,hence fixing the VBV macroblocking
issue that comes due to lack of frames in the Lookahead at the end of the video.
