dev-libs/opencl-clang: pass $LLVM_MAX_SLOT to get_llvm_prefix()

When invoked without max_slot, get_llvm_prefix() iterates over *all*
LLVM slots known to llvm.eclass - including those exceeding LLVM_MAX_SLOT.
As a consequence, an ebuild can e.g. end up getting installed into llvm:9
directories in spite of having been linked against llvm:8.
