The "Linux guest support" menu is preexisting.  This patch just moves it
verbatim from "Processor type and features" to "Virtualization".  My
logic is that "Linux guest support" has a heck of a lot more to do with
"Virtualization" than the processor.

I think it's kinda silly to have folks chase through two levels of menus
when the submenus would have both fit on the screen anyway.  Let's save
the layers of nesting for when we have 150 items in a menu.

I'll have new patches out in a sec.
