TYPO: fix filenames for O3 replay
The reading of the low-latency data stream is failing for the O3 replay which we tracked down to a typo in the filename being queried.
The filenames look like the following, which should be caught by the new setup.
$ ls /dev/shm/kafka/H1
H-H1_llhoft-1370620070-1.gwf
$ ls /dev/shm/kafka/H1_O3ReplayMDC
H-H1_O3ReplayMDC_llhoft-1370620047-1.gwf
