Gyan Doshi 74b14ccd31 lavc/libx265: unbreak build for X265_BUILD >= 210 
x265 added support for alpha starting with build 210.
While doing so, x265_encoder_encode() changed its fifth arg to
an array of pointers to x265_picture. This broke building lavc/libx265.c

This patch simply unbreaks the build and maintains existing single-layer
non-alpha encoding support.

Fixes #11130
