[Service] Change privilege condition for application.launch / launchAppControl

Confirmed with privilege member, in privilege db, If declare an application.launch
privilege, the app will not have an application.launch privilege, but an
appmanager.launch privilege, so add "appmanager.launch" in privilege precondition,
otherwise service app can not use tizen.application.launch() /
tizen.application.launchAppControl().
