[Cin] Lcms2 integration

[Andrew Randrianasulu]

So I played around lcms2 2.13.1 integration in cingg build system for
ffmpeg and it appear to work - at least build works and I can see
iccgen/iccdetect filters ...

Note, lcms2 tarball not included due to size

Note that ffmpeg also demand lcms2 >= 2.13

We also can try and get  in ffmpeg.git patches hopefully enabling
automatic icc profile support at least for input images ...
