If the tur checker is run, and the tur_thread has timed out,
libcheck_check() doesn't actually check if the thread is still running.
This means that the thread could have already completed successfully,
but the tur checker would still return PATH_TIMEOUT, instead of the
value returned by the thread. This patch makes libcheck_check() actually
check if the thread completed, and if so, it returns the proper value.
