Fix problem that -log_dir will not be respected when anything is logged before flag.Parse().
Before this change, premature logging resulted into log files being put in the default location (e.g. /tmp), but not the one specified by the log_dir flag.
After this change, premature logging will not result into the creation of the log files yet. Instead, the log message will be printed to stderr.
