Fix intra prediction ref selection in skip_encode

Browse Source 
This commit fixes the intra prediction reference source selection
in the settings of skip_encode. Use original boundary pixels as
prediction reference, when the inverse transform and reconstruction
are skipped in the per block size rate-distortion optimization loop.
