Arch's cloud image enables systemd-time-wait-sync, and sshd is ordered
after pacman-init, which waits for time-sync.target. Once provision.sh
turns off systemd-networkd, systemd-timesyncd thinks it's offline and never
syncs, so every boot after the base build waited forever and the installed
image's build failed with "The VM didn't answer on SSH".
