[llvm] [LLVM] Silence compiler-rt warning in runtimes build (PR #99525)

[Joseph Huber via llvm-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/99525

Summary:
The `compiler-rt` project wants `LLVM_CMAKE_DIR` but the
`llvm_ExternalProject_add` interface sets the `LLVM_CONFIG_PATH`. This
patch just makes the utility pass that as well.
