Bug 13748: Acquisition wizard: some strings not translatable

Bug 13748: Acquisition wizard: some strings not translatable

This patch removes all instances of CGI::scrolling_list from
reports/acquisitions_stats.pl, which prevented proper translation

To test:
1) Install and enable a language (es-ES or de-DE are good choices)
2) On Acquisitons wizard, some pulldown labels are not translated
3) Apply the patch
4) Update and install again the language
5) Check labels are translated and all pulldown works

This does not solve the 'Collection code' problem,
is more strange

Followed test plan, works as expected.
