cmake: Support exports correctly with LLVM_DISTRIBUTION_COMPONENTS

We need to apply the same export logic in clang as in llvm for
LLVM_DISTRIBUTION_COMPONENTS, or the clang exports will be invalid
when we use this config.

This makes using distribution components without setting
LLVM_TOOLCHAIN_ONLY=On work correctly.
