Project Kunai associates cloud account with a mix of various items, including board serial number, resulting in several machines being bound to the same cloud account because the momo serial number is always empty.
Note: this patch doesn't follow the systemd guidelines of not exposing directly /etc/machine-id content (but Wine already exposes /etc/machine-id as Windows machine GUID).
