Bug 14275: Remove CGI::scrolling_list from guided_reports.pl

Remove an instance of CGI::scrolling_list from this file

To test:
1) Go to Reports, Guided report wizard, New SQL report

2) Create a report with some auth value list, e.g.

SELECT surname,firstname FROM borrowers WHERE branchcode=<<Enter patrons library|branches>>

Save

3) Clic on 'Run this report", look at the dropdown, that will be changed

4) Apply the patch

5) Reload, check dropdown and any regression

Followed test plan, works as expected.
