Subject: [PATCH] pthread: implement sem_destroy
Note that we don't allocate memory in sem_init: we are using placement new to
just construct the object over an already existing memory location. Therefore,
all we need to do is release our unique_ptr
Thanks Pawel for noticing we need to release memory of the internal semaphore
