mesa: don't add extra tags to the libopencl-mesa package

The libopencl-mesa package provides OpenCL ICDs (Installable Client
Drivers). As such, there is no conflict between several packages
providing ICDs for different vendors. Split the loop that modifies
package metadata and stop adding extra RPROVIDES / RCONFLICTS /
RREPLACES tags to the libopencl-mesa package.
