tcp: Replace custom WaitList with ConditionVariable.
The WaitList implementation had a race condition between checking for
the condition and acquiering the semaphore. If a thread was rescheduled
at that point, the signal could be missed due to the use of
release_sem_etc() with the B_RELEASE_ALL flag while the thread was not
yet waiting for the semaphore. The transfer would subsequently stall.
