Bug 21704: (follow-up) Remove unused 'frameworkcode' template param

This patch removes the 'frameworkcode' template parameter. Now the
'framework' object is passed, and everytime the frameworkcode is needed
on the template, framework.frameworkcode is called.

To test:
- Apply this patch
- Run:
  $ grep ' frameworkcode ' koha-tmpl/intranet-tmpl/prog/en/modules/admin/marctagstructure.tt
=> SUCCESS: There's no use of 'frameworkcode' in the template
- Sign off :-D
