[scudo] Check the return values of the pthread_* functions

Summary:
Currently we are not enforcing the success of `pthread_once`, and
`pthread_setspecific`. Errors could lead to harder to debug issues later in
the thread's life. This adds checks for a 0 return value for both.
If `pthread_setspecific` fails in the teardown path, opt for an immediate
teardown as opposed to a fatal failure.
