Bug 34334: Item(s) in MARCdetail untranslatable

This patch adds a <span> around the text "Item(s)" in the template for
the MARC detail page in the staff interface. Without the span the
translation tool can't detect the string.

To test, apply the patch and update a translation, e.g. fr-FR:

  > cd misc/translator
  > perl translate update fr-FR

- Open the corresponding .po file, in this case
  misc/translator/po/fr-FR-staff-prog.po
- Confirm that the string is now in the .po file for translation. You
  should find these lines:

koha-tmpl/intranet-tmpl/prog/en/modules/catalogue/MARCdetail.tt:146
c-format
msgid "Item(s)"
msgstr "Exemplaire(s)"

I found that the translation was already populated. Install the updated
po file:

 > perl translate install fr-FR

Test the MARC detail page in your translated language to confirm that
the string is correct.
