[Rpm-ecosystem] Requires based on destination hardware

[Igor Gnatenko]

It is already implemented, but I'm thinking how to make better dependencies
on opencl realizations. For example, we have program which uses OpenCL, but
how we can provide to user one of implementations of OpenCL? First idea
which comes to my mind to make Provides: opencl to all implementations and
Requires: opencl in this program, but it is not looks very good..
