AlarmManager: Store time offset system property 

For TILB (time in low battery mode) we need to store the time zone
offset as a system property. Updating AlarmManagerService so it matches
kr3-dev and stores this offset when the time zone is updated through
connectivity or when it is updated manually in the settings.

Bug: 311191984
Test: Update time zone manually and check the system property
