lxc-plamo: various small changes

- Change redirection of fd 200 to 9 (greater than 9 may conflict with
  fd the shell uses internally)
- Replace numeric line addressing of ed to regular expression to avoid
  correcting the line addressing at each modification of init scripts
- Correct the option order (trivial)
