Bug 13362: translate script creates dirs on update

A dir creation was uncommented (by me), the effect is
create a lang dir on 'update', which is no needed.

To test:
1) Update translation files for a uninstalled language
(cd misc/translator; ./translate update xx-YY)

2) Check new dirs
koha-tmpl/opac-tmpl/bootstrap/xx-YY/
koha-tmpl/intranet-tmpl/prog/xx-YY/
koha-tmpl/intranet-tmpl/prog/en/modules/help/xx-YY/

3) Clean all
git clean -f -d

4) Apply the patch

5) Repeat 1) (i.e. update)

6) Check no new dirs this time
