Duplicate the last_install content into last_log.
Currently we save the OTA metrics in last_install, which keeps the data
for the _last_ install only. This CL logs the same content into last_log
so that we keep the metrics for every install.
Bug: 31607469
Test: Apply an update (via OTA and sideload) and check last_log and last_install.
