Bug 12707: Remove CGI::scrolling_list from some Reports

Bug 12707: Remove CGI::scrolling_list from some Reports

This patch removes similar instances on 5 files, same code.
Also removes a commented one, changed in case some plan to
resurrect the code.

This bug depends on Bug 12696.

In all cases but the commented one, what was replaced
is a pulldown with one value, 'CSV'

To test:
1. Apply patch for Bug 12696
2. Apply this patch

Check for the pulldown 'Into an application'

3. Go to Reports > Statistics wizard > Borrowers
4. Go to Reports > Statistics wizard > Circulation
5. Go to Reports > Statistics wizard > Holds
6. Go to Reports > Top lists > Most-circulated items
7. Go to Reports > Inactive > Patrons who haven't checked out

8. There is also a commented code on catalogue_stats, no fuctional
changes.

Followed test plan. Patch behaves as expected.
