clang.bbclass: Do not export llvm-config variables

exporting them changes signatures of the tasks for all recipes
includeing native ones, so when meta-clang is not used it ends up
building all native recipes too. Defining these variables is good
enought for clang to see them in do_compile shell for target recipes
