Subject: [PATCH 2/3] FreeBSD: Testing: pthread handling

Fixing pthread usage in tsan and tsan-inout tests. pthreads are imported
as opaque pointers on FreeBDS, and thus need to be kept in an optional
pthread_t, like on Apple platforms.

Unlike on macOS, pthread_join is not annotated with nullability
annotations and thus takes an optional opaque pointer, so we don't need
to unwrap it.
