pctl: refactoring IParentalControlServiceFactory and IParentalControl… (#1219)

* pctl: refactoring IParentalControlServiceFactory and IParentalControlService call

Our previous implementation was totally guessed. Now it's implemented according to RE, even if it's stubbed because we will not support Parental Control for now.

* unknownFlag > permissionFlag
