restore: strip Firmware.UUID if the target VM is new
restore: strip Firmware.UUID if the target VM is new

Otherwise two different VMs will end-up having the
same UUID which is incorrect by definition.

This would also lead to other issues like causing
cloud-init to not change the VM's instance-id and
therefore not regenerating ssh-keys and re-setting
the hostname.
