oeqa/runtime/cases/parselogs.py: ignore a message from watchdog

The following message from watchdog is not an error.

  "error retry time-out = 60 seconds"

Checking watchdog's source codes, we have:

  src/watchdog.c: log_message(LOG_INFO, "error retry time-out = %d seconds", retry_timeout);

It's clear this is an info message, so parselogs should ignore it.
