If you want the horizontal (gloal) nav bar, you can configure through Site Settings => Navigation settings. However, if you only want it in the layout, you should create a new one based on the Search results layout. Open SPD, Page Layouts, New Page Layouts and copy the Search results html. To get the global nav in there, you should be able to grab it from one of the default master pages. There are also other menu / nav types in the snippet gallery you can copy and paste into your new layout
