pkg-config patch from debian

There are bugs with the pkg-config file supplied by the opencv[-core] ports. This makes it so that the gstreamer1-plugins-opencv doesn't actualy link against the needed libraries. Attached is a patch from debian which resolves this problem. The problem has also been reported upsteam.

The out put on Debian:
