Correct NetBSD support in pthread_once(3)/TSan
Summary:
The pthread_once(3)/NetBSD type is built with the following structure:
struct __pthread_once_st {
pthread_mutex_t pto_mutex;
int pto_done;
};
Set the pto_done position as shifted by __sanitizer::pthread_mutex_t_sz
from the beginning of the pthread_once struct.
This corrects deadlocks when the pthread_once(3) function
is used.
