multimedia/x264: add OPENCL option, enabled by default

Before OpenCL can be used for lookahead install at least one
implementation: devel/freeocl, devel/pocl, lang/beignet or lang/clover.

  $ x264 --fullhelp | fgrep opencl
	--opencl                Enable use of OpenCL
	--opencl-clbin <string> Specify path of compiled OpenCL kernel cache
	--opencl-device <integer> Specify OpenCL device ordinal

where the options also work in other apps e.g.,

  $ ffmpeg -i <input-file> -codec:v libx264 -x264opts opencl:opencl-device=1 <output-file>
  $ mpv --ovc libx264 --ovcopts-add x264opts=opencl:opencl-device=1 -o <output-file> <input-file>
