[PATCH V3 4/4] rust: Fix rust build failure

Target LLVM tools are installed in the sysroot because they are needed
for llvm-lit to run tests. However, this leads Rust to pick up a target
llvm-config that cannot run on the host. Overwrite it with the native
llvm-config so Rust can execute it correctly.
