Make sure logs volume has apache and koha directories

- This make the log forwarding to vm-devops work, but it's not a
  good solution, since the koha instance name is hard coded.

- The ideal would be if the logs volume is somehow mounted when
  koha_container image starts building, and therefore would get
  all directories in /var/log. But I can't for the life of me
  figure out how to set it up.
