RESTRICT AUTOMERGE Turning off wtf logging for alarm limit

The issue is not happening frequently enough for the large amount of
logging to be justfied. A bugreport should still contain the full list
of alarms when the caller is a core system uid. This should be enough
for debugging critical crashes.

Test: Builds, existing tests pass.
adb logcat -s AlarmManager
