obmc-initfs: shutdown when rofs is a loop mounted image in /run

If one sets rodir=/run/image-rofs roopts=ro,loop and transfers
an image one can run from a base image in ram.  However, the
shutdown will fail to unmount /run because it is busy and then
fails to unmount /cow which causes oldroot to be still mounted.

By moving the mount to the side everything cleans up (as long
as there are no other mounts under run, and systemd-shutdown
tried to do as much as possible).
