Allow BAL from PrintServiceSettingsFragment

This fixes the info button on the printer in the printer list (the call
is from the system (uid=1000) and needs to allow BAL to start the
activity).

This only opts in sending a single pending intent to the previous (pre U) behavior which allows BAL. Therefore the risk of the change is minimal. This was reported by an external partner.
