osd: fix container reboot

It's sad but we can not rely on the prepare container anymore since the
log are flushed after reboot. So inpecting the container does not return
anything.
Now, instead we use a ephemeral container to look up for the
journal/block.db/block.wal (depending if filestore or bluestore) and
build the activate command accordingly.
