KVM: selftests: Move page_align() to shared header

Browse Source 
To avoid code duplication, move page_align() to the shared `kvm_util.h`
header file. Rename it to vm_page_align(), to make it clear that the
alignment is done with respect to the guest's base page size.

No functional change intended.
