Nirbheek Chauhan 1536f30cc2 openjpeg: Port to 2.1 and require a pkg-config file for 2.0 and 2.1 
The port was trivial, and according to the NEWS file nothing else has changed,
but it is possible that other API was changed without proper notification.

OpenJPEG upstream has shipped a pkg-config file for the past 4 years, and all
distros should be shipping it by now.
