Subject: [PATCH] configure: try to use pkg-config to find libopenjpeg

Beginning with version 1.5.1 openjpeg defaults to install its headers to
/usr/include/openjpeg-${major}.${minor} instead of /usr/include making
the old test fail.
Instead of guessing the openjpeg major and minor versions we use
pkg-config for newer openjpeg versions.
For older versions (<1.4.0) we continue to use the old test as the .pc
file was added in version 1.4.0 and ffmpeg still works for these versions.
