Repair PRL Update and replace some system/apps
-- SprintDM.apk and SprintSyncMLSvc.apk appear to be necessary for PRL updates
-- Activation.apk may have other dependencies that have been removed, needs testing
-- Music2.apk to replace Music.apk, even though most probably use third party players
-- ChromeBookmarsSyncAdapter.apk was removed by accident
-- Samsungservice.apk and SPPPushClient_Prod.apk  in case they are needed for activaton (probably not)
