Gyan Doshi f3eb622fc4 avcodec/libx265: unbreak build for X265_BUILD >= 213 
Earlier, x265 made an API change to support alpha and
other multiple layer pictures. We added guards to accommodate
that in 1f801dfdb5

They have now reverted that API change in
78e5b703b1

Updated our wrapper guards to unbreak build again.
