dev-libs/amdgpu-pro-opencl: conflict with media-libs/mesa[opencl]

With both this and the Mesa OpenCL state tracker enabled, using
dev-libs/ocl-icd one ends up with two OpenCL platforms pointing
to the same hardware - and more importantly causes segmentation faults
in all applications attempting to use OpenCL.
