Put all config options needed to run Linux as a guest behind a CONFIG_HYPERVISOR_GUEST menu so that they don't get built-in by default but be selectable by the user. Also, make all units which depend on x86_hyper, depend on this new symbol so that compilation doesn't fail when CONFIG_HYPERVISOR_GUEST is disabled but those units assume its presence. Sort options in the new HYPERVISOR_GUEST menu, adapt config text and drop redundant select.
