x265 update to 1.6 (ABI bump)

[Dominik 'Rathann' Mierzejewski]

Dear All,
1.6 update was requested:
https://bugzilla.rpmfusion.org/show_bug.cgi?id=3593

It looks pretty clean and the only two users ffmpeg and vlc rebuild
cleanly against this new version, so I updated it.

ffmpeg is rebuilt already, but I don't have ACLs for vlc. 
Please bump and rebuild before pushing.

Regards,
Dominik
