Bug 10261: Link to patron files missing from circ-menu.tt

The link to patron files doesn't appear on some pages. That's because
the link was added to circ-menu.inc but not circ-menu.tt. Each is used
by different patron-related pages. This patch adds the missing link.

To test, enable the EnableBorrowerFiles system preference and view
members/pay.pl or members.paycollect.pl. The "Files" tab should appear
in the left-hand sidebar menu. Other patron pages should show the same.

Edit: Corrected scope of template variables which shouldn't have been
copied directly from circ-menu.inc without changing scope.
