Changed background_rollback to return true/false depending on if

Browse Source 
background rollback did happen.
Background rollback should be skipped if the aborting happens due to KILL command issued by user.
Some KILL signals, like KILL CONECTION, wake up the victim too early so that background rollback
could happen in parallel with the victim waking up and continuing execution.
