Bug 23700: Fix output of koha-plack --restart
To test:
- Run "sudo koha-plack restart kohadev" and verify the output is
  out of line.
- Apply the patch
- If you are on e.g. kohadevbox you need to copy koha-plack to
  /usr/sbin/ thus:
  sudo cp debian/scripts/koha-plack /usr/sbin/koha-plack
- Run "sudo koha-plack restart kohadev" again and check that you
  get two lines of output, nicely aligned with the "OK" inside the
  square brackets.
