layer.conf: disable conflicting LLVM PACKAGECONFIG options

The LLVM package in OE-Core got optional support for building libclc and
SPIRV-LLVM-Translator. However this also means that llvm-native also
install clang binaries into the sysroot. In order to remove a conflict
with the clang recipe from meta-clang forcibly disable PACKAGECONFIG
options causing conflict.
