Bug 16159 - guarantor section missing ID on patron add form

In the patron entry form template most <fieldset> and <legend> tags have
unique ids. This patch adds ids to fieldsets and legends which lack
them.

To test apply the patch and view the patron entry form. There should be
no visual changes. There should be no HTML validation errors triggered
by this change.
