Subject: [PATCH] Ensure DOKU_INC is always right using an auto_prepend_file

This is basically the same fix as bitnami/containers#12535

Plugins or template may have their own entry points. Eg. the sprintdoc
template's svg.php

Those entrypoints usually start with something like:

```
if(!defined('DOKU_INC')) define('DOKU_INC', __DIR__ . '/../../../');
require_once(DOKU_INC . 'inc/init.php');
```

Since plugins are installed in the volume, __DIR__ will point to the
wrong location. By predefining DOKU_INC before any other code runs, this
can be avoided.
