Fix buildbot failures after r359159.
std::mutex was not actually is_nothrow_default_constructible in C++98/C++03,
because the variable declaration
... could throw an exception from the mutex destructor. Fix it by marking the
destructor as non-throwing. This has no effect in C++11 onwards, because
destructors are non-throwing by default in those language modes.
