explicitely install findutils pkg in final img

- find is used by some of the mover scripts (rclone, rsync-tls)
  and now that we've removed the perl package and all it pulled in,
  we get find via the findutils package.
- This happens when we run: `microdnf --refresh update -y`. This
  change is to explicitly pull in findutils in case anything changes
  in the future with packaging and it isn't automatically installed.
