selection: selection_on_rows(): use scrollback relative coords

Browse source 
When checking if the current selection intersects with the
region (passed as parameter to the function), use scrollback relative
coordinates.

This fixes an issue where selections crossing the scrollback
wrap-around being misdetected, resulting in either the selection being
canceled while scrolling, even though it wasn’t scrolled out, or the
selection _not_ being canceled, when it _was_ scrolled out.
