[libc] Fix return value of __cxa_thread_atexit_impl function. (#122171)
This has been added in 0071a79532e8d664b734956a431d8c8c942cc25e to
support TLS destructors. Return value of __cxa_thread_atexit is supposed
to be the same as std::atexit - zero on success, non-zero on failure.
Update the code to do just that (also be consistent with llvm-libc's
existing atexit / at_quick_exit implementations).
