provisioner: explicitly sync state file on writes

Scripts sometimes reboot the preload VM with sysrq-trigger. This type of
reboot will not sync any pending writes to disk. This can result in the
state file not being up to date on the next reboot.

One consequence of this is potentially running some steps multiple
times, when they shouldn't be run multiple times. Let's avoid this by
explicitly syncing the state file on every write.
