[HDFS-3267] TestBlocksWithNotEnoughRacks races with DN startup

Description

In TestBlocksWithNotEnoughRacks.testCorruptBlockRereplicatedAcrossRacks, it restarts a DN, and then proceeds to call "waitCorruptReplicas". But, because of HDFS-3266, it doesn't actually wait very long while checking for the corrupt block to be reported. Since the DN starts back up asynchronously, the test will fail if it starts too slowly.
