Userland: Actually use the correct character map index from KeyEvent

Browse source 
Instead of using a scan code, which for scan code set 2 will not
represent the expected character mapping index, we could just use
another variable in the KeyEvent structure that correctly points to the
character index.

This change is mostly relevant to the KeyboardMapper application, and
also to the WindowServer code, as both handle KeyEvents and need to
use the character mapping index in various situations.
