Bug 12697 - Surplus closing </div> in OPAC advanced search (bootstrap)

In koha-tmpl/opac-tmpl/bootstrap/en/modules/opac-advsearch.tt template,
there is a surplus closing </div> in line 336 (= line 332, in case
Bug 12521 is applied first):

   336: </div> <!-- / .span4 -->

which causes some minor layout problems for this page - i.e.: page
footer ("Powered by Koha" + custom footer set up in system prefrences -
if any) is "glued" to the bottom (to the language selection bar);
unless Bug 12521 is applied first, this affects the placement of the
2nd search bar as well.

To reproduce:

1/ go to the OPAC advanced search page
2/ zoom out (e.g., use Ctrl-<minus> several times) and obeserve the
result
3/ no need for step 2/ (zooming out) when using a display with
(relatively) high vertical resolution; also, this particullar problem
gets more apparent/more noticeable with MARC21/USMASRC "subtype"
options being hidden in the OPAC advanced search (Bug 9043).

To test:

1/ ensure that Bug 12521 is applied first/already applied
2/ apply patch
3/ confirm that this issue is no longer reroductible

On top of 12521, don't know exactly what to reproduce, but
surplus '</div>' is real (33 open, 34 close).
Everything looks correct, no koha-qa errors.
