parselogs.py: ignore rdrand initialization failure

On the system whose cpu doesn't support rdrand,
there comes below message when start rngd service
 #systemctl status rngd
 [snip]
 Feb 25 05:08:14 qemux86-64 rngd[133]: [rdrand]: Initialization Failed
 [snip]

Actually the failed message doesn't matter as it
only indicates one entropy source as rdrand fails
to initialize and won't affect rngd function.

So add to ignore the failure message to fix below
error during do_testimage:
NOTE: ======================================================================
NOTE: FAIL: test_parselogs (parselogs.ParseLogsTest)
