factory_install: sync after installation is completed
The default action after factory installation is reboot.
However, there might be some buffered data needs to be synced
into disk at that time, ex: part of release image.
It has been observed in factory that the 'reboot' might be
related to the issue 'Chrome OS is missing or damaged' after
factory wipe. Add a sync/sleep to write any data buffered in
memory out to disk before reboot.
BUG=None
TEST=setup mini-omaha server and install a factory bundle on DUT
