Fix log handlers to work for both syslog and rsyslog

Update the [handler_production] and [logger_root] parameters in
logging.conf in order to ensure the logs are written to the
syslogd daemon.

Update to use the /dev/log socket from the syslogd daemon so that
the logging works for both rsyslog and syslog.
