meta-quanta: gbs: add system event sensor to handle non-IPMI-SEL

Since the phosphor-logging still has other event
types other than IPMI SEL and also put them in the
"/var/lib/phosphor-logging/errors" directory. It
would make "ipmitool sel list" result in the
unspecified error

Thus, map these logs to the system event sensor as
"Undetermined system hardware failure"
