QKeyMapper for Symbian does not initialize keyboard related member data

Symbian specific implementation of QKeyMapper does not initialize keyboardInputLocale nor keyboardInputDirection.

This leads to getting strange return values when using APIs to retrieve the related functionality.

I.e. call QApplication::keyboardInputDirection() to get keyboard direction; instead of Qt::LeftToRight (or Qt::RightToLeft),
return value is unspecified (some random value).
