The file '/usr/lib/libcttmetrics.so' will generate a conflict
with the upcoming libvpl-tools package.

Also added 'vpl-runtime' to intel-media-sdk provides.

The previous update was made by a non-maintainer without
any discussion (a really bad practice in my humble option),
forcing me to remove the opencl plugin now. The opencl plugin
relies/validates on specific versions of the Intel opencl
stack, and the last update may have potentially broken it.
