In the anonymous python function that creates packages based
on PACKAGECONFIG, use a single synthetic "opencl" setting
that is added when either "clover" or "rusticl" are present.

Without this, creating variables for two "libopencl-mesa" will
confuse the packaging code, resulting in subsequent packages
(like mesa-megadriver and others) being renamed incorrectly.

This also makes sense from a packaging standpoint: currently
both clover and rusticl can be enabled, in which case both CL
frontends should go into the same libopencl-mesa subpackage.
