poznote: follow init.sh into docker/

6.87.0 moved init.sh from the repository root to docker/init.sh, so the
update stopped at

  chmod: cannot access '/opt/poznote/init.sh': No such file or directory

The file itself is byte for byte the same and uses absolute paths only,
so running it from the new location changes nothing. Prefer docker/ and
fall back to the old path, since a container pinned to an older release
still has it there.
