LibGUI: Calculate row position for scroll into view

Browse source 
When a user is navigating a table view with arrow keys and a row is
outside of the current view, then scroll_into_view is called, and the
position of the rectangle passed to this should take into account the
column headers.

This can be seen making more pleasant the navigation in the System
Monitor in the Processes view, for example.
