opencv: Upgrade to 2.4.11

Upgrade OpenCV to the 2.4.11 release.

Remove the opencv-fix-pkgconfig-generation patch which has been integrated upstream,
be it in modified form.
Disable 1394 support by default to get a deterministic build.
Fix "jasper" dependency, the BUILD_JASPER parameter served only to build an internal
library, while WITH_JASPER actually controls whether jpeg2000 support was desired.
