Siavash Sameni 0224ce654c step E.2: shrink cpp_smoke to std::atomic only — no thread, no mutex ...

Incremental bisection within Step E. E.4 (atomic + mutex + thread) still
crashed at __init_tcb. Drop mutex and thread, keep only std::atomic.
Build.rs still emits cargo:rustc-link-lib=c++_shared via
cpp_link_stdlib('c++_shared'), so the NEEDED entry for libc++_shared.so
in the final .so stays identical. Goal: if this crashes, the issue is
purely the dynamic link against libc++_shared (not thread/mutex code).
If it passes, the issue is actually std::thread or std::mutex use.
