shutdown: readd explicit sync() when shutting down
As it turns out reboot() doesn't actually imply a file system sync, but
only a disk sync. Accordingly, readd explicit sync() invocations
immediately before we invoke reboot().
This is much less dramatic than it might sounds as we umount all
disks/read-only remount them anyway before going down.
