battery_mitigation: Fix lastmeal timestamp

Browse source 
Lastmeal.txt may be generated from after device rebooted from IRQ
triggering.  By applying limit on the time when it generates,
lastmeal.txt will not be generated after device rebooted.

Bug: 246817058
Test: Trigger brownout and confirm lastmeal.txt has correct timestamp
