Dmitry Vyukov c7081b5b4c tsan: fix crash during thread exit ...

Use of gethostent provokes caching of some resources inside of libc.
They are freed in __libc_thread_freeres very late in thread lifetime,
after our ThreadFinish. __libc_thread_freeres calls free which
previously crashed in malloc hooks.
Fix it by setting ignore_interceptors for finished threads,
which in turn prevents malloc hooks.
