When performing a reboot, do a sync before starting the shutdown.
A really long sync can cause what should otherwise be a fairly
short operation to take a long time. Raising the timeout on the
wait_down command could potentially mask other real issues, so
instead lets just do an explicit sync as a seperate operation.

Risk: Low
Visibility: Having a ton of data to be sync'd shouldn't lead to
wait_down timeout on a reboot.
