Accepting request 225779 from KDE:Extra

- Upstream now provides tarballs with source only as git tags
  from github so update Source0 path.

- Add requires on various X extensions linked to opencv_ts module.
  As those are present in the .pc file we need it anyway.

- Update to OpenCV 2.4.8
  More info at:
  http://opencv.org/opencv-2-4-8.html
