If host_ram_size() * RAM_SIZE_RATIO does not result in a value
aligned to the host page size, it triggers an error in
__kvm_set_memory_region(), called via the
KVM_SET_USER_MEMORY_REGION ioctl, which requires the size to be
page-aligned.
Fixes: 18bd8c3bd2a7 ("kvm tools: Don't use all of host RAM for guests by default")
