[DSRM] Shift the phone id value due to proto limitations

Symptom: If we use the values 0 and 1 for the phone ID,
         when the device uploads the metrics with the old ROM,
	 they will be mixed up(default value is 0).

- To avoid this problem, we shift the value and it can filter out the old and new data.

Bug: 260166714
Test: Manual test passed
      Telephony sanity test passed. Result: b/269436482.
