dual-image: remount alt partitions during update
When the BMC is to updating the alt image, it needs to stop the sync
manager, umount the rofs/rwfs-alt partitions before the flashing,
mount them after it's done, and restart the sync manager.
Otherwise the mount point of rofs/rwfs-alt will get error because the
content is updated.
Tested: Verify the rofs/rwfs-alt are umounted during the alt flashing,
and are mounted again after the flashing is done, and the sync
manager is restarted.
