Frameworks: activate PIE on lockscreen apps

currently the situation was that every application started on
lockscreen had disabled pie (because lockscreen disables it). Downside
on incoming call or camera widget the user did not have a navigation.
As well on unsecure lockscreen the user could not navigate further

this commit fixes this behaviour
