Subject: x86/vsdo: Fix build on PARAVIRT_CLOCK=y, KVM_GUEST=n

From: Andy Lutomirski <luto@kernel.org>

commit 8705d603edd49f1cff165cd3b7998f4c7f098d27 upstream.

arch/x86/built-in.o: In function `arch_setup_additional_pages':
 (.text+0x587): undefined reference to `pvclock_pvti_cpu0_va'

KVM_GUEST selects PARAVIRT_CLOCK, so we can make pvclock_pvti_cpu0_va depend
on KVM_GUEST.
