Disable ScheduledJobConstraintChanged logging for now.

+ No metrics or experiments are using this atom. Disabling it does not do any harm.
+ This atom is too frequent during boot time and causes socket buffer overflow. Other
  important events from system server may drop.

We can re-enable the logging once we figure out what metrics we are going to have.
