Add one second timer to save POST codes to file

A lot of POST codes are sent to BMC from BIC
in a short time.

In BMC, there is an ipmi handler to get POST codes
and upload to dbus property.

The xyz.openbmc_project.State.Boot@.PostCode service
listens the PropertiesChanged signal and saves to POST
codes history file.

The xyz.openbmc_project.State.Boot@.PostCode service
is hanged if there are too many POST codes in a short time.

At this time, the memory usage of dbus-broker increases,
and the out-of-memory(OOM) issue happens.

The processes are killed when OOM happens,
and BMC may reset unexpected.

Test Case:
Check the frequency for post code file getting larger
