installer: Add smbios serial ds=nocloud for --cloud-init

This is a hint to cloud-init that we are passing in a nocloud

Ubuntu -kvm-disk cloud images since at least 20.04 need this to
work with -M q35:
https://bugs.launchpad.net/cloud-init/+bug/1940791

Fixes: https://github.com/virt-manager/virt-manager/issues/359
