telephony: SignalStrengh: Don't calculate a LTE snr if the srq is invalid

If the previous values are invalid and signal quality is -1, chances are there's
no LTE signal at all, so don't calculate the SNR and mark it invalid as well.

This fixes the strength indicator in GSM devices where it was being skewed
by the ghost LTE value

AppOps: Don't apply OP_ALARM_WAKEUP to system components
System can freely invoke and manage alarms. Preventing it from doing
so interferes with remote components like the backupmanager (backing up alarms)
due to the mismatched uids between the invoking app and the running
service that takes the action.
