There is a configuration option send-to-logger[1] that changes the
behavior of `IpmiSelAdd`.
With the config enabled, `IpmiSelAdd()` sends the log to
phosphor-logging service and becomes an entry in
/xyz/openbmc_project/logging/entry/, instead of saving the message in
/var/log/ipmi_sel.
And ipmid will parse the entry into an SEL record.
