[tsan] Don't symbolize stack traces if dl_iterate_phdr is not ready (#143199)
When a CHECK() fails during TSan initialization, it may segfault (e.g., https://github.com/google/sanitizers/issues/837#issuecomment-2939267531). This is because a failed CHECK() will attempt to print a symbolized stack trace, which requires dl_iterate_phdr, but the interceptor may not yet be set up.
This patch fixes the issue by not symbolizing the stack trace if the dl_iterate_phdr interceptor is not ready.
