Fix end_line incorrectly assigned from start_line in CSV output #4785

In flatten_scan(), the end_line field for copyrights, holders, and
authors was assigned copyr['start_line'] instead of copyr['end_line'].
This caused the end_line column in CSV output to always equal
start_line, losing the actual end line information.
