Subject: opencv: bump version to fix ffmpeg support build

A newer version of opencv is needed after the ffmpeg version bump. This
version does need a minor patch for fabsl on uClibc though.

+
+[PATCH] Fix compile issue in flann module on uClibc without long double support
+
+uClibc configured without UCLIBC_HAS_LONG_DOUBLE_MATH (because of user
+choice or simply that the arch doesn't provide long doubles) doesn't
+provide fabsl(), breaking the build in the flann module.
+
+Work around it by not providing the long double template specialization.
