clang: remove PROVIDES:append settings

With these settings, we'll have multiple providers of llvm. This means
that with pristine poky master + meta-clang master, we'll have some
output like below:

  NOTE: Multiple providers are available for llvm-native (llvm-native, clang-native)
  Consider defining a PREFERRED_PROVIDER entry to match llvm-native

And when running 'bitbake world', we'll get error messages like below:

  ERROR: Multiple .bb files are due to be built which each provide llvm-native:
    virtual:native:/PATH/TO/poky/meta/recipes-devtools/llvm/llvm_19.1.4.bb
    virtual:native:/PATH/TO/Yocto/poky/meta-clang/recipes-devtools/clang/clang_git.bb

As the README.md has already specified how to use this layer, let's
remove such settings before sorting things out.
