Bug 10422 - Remove references to unused and non-existent wizard.css

Bug 10422 - Remove references to unused and non-existent wizard.css

doc-head-close.inc contains a reference to "wizard.css" which doesn't
exist. The option to include it never evaluates as true, and that
section can be removed from the template.

To test, apply the patch and view any page in the staff client.
Everything should be styled as before. A search of the Koha source
should return no references to "wizard.css" or a "wizard" variable.
