opencv: don't download during configure
OpenCV downloads data files during the CMake configure phase, which is bad because fetching should only happen in do_fetch (and if proxies are needed, won't be set in do_configure). The recipe attempts to solve this already by having the repositories in SRC_URI and moving the files to the correct place before do_configure(). However they are written to ${B} which is then wiped in do_configure so they're not used. The OpenCV download logic has a download cache with specially formatted filenames, so take the downloaded files and populate the cache.
