testsuite/smokey/xddp: Poll for registry link to appear
Registry updates happen asynchronously, and the NRT thread may fire up
before this. So spin until we find the desired entry. This avoids
sporadic test failures with open() failing on fast multicore machines.
Remove the unused and misleading sem_post from thread2 at this chance.
