Added a path to the drupal8 path candidates to find civicrm.config.php

[kainuk]

Overview

Change is a fix for a civibuild error. When civibuild is run with the type drupal8-clean it fails on the sql install script generation. The reason is that it cannot find civicrm.config.php file. This patch adds another location to search for this file.

Before

Civibuild create drup8 --type=drupal8-clean throws the following error:

PHP Fatal error:  Uncaught Exception: Failed to locate template for civicrm.config.php in /home/klaas/buildkit/build/etuc/libraries/civicrm/CRM/Core/CodeGen/Config.php:29
Stack trace:

#3 {main}

thrown in /home/klaas/buildkit/build/drup8/libraries/civicrm/CRM/Core/CodeGen/Config.php on line 29

After

Civibuild generates to installation files and goes to the next step.

Technical Details

The search locations are extended not replaced.

I don't think there is any risk here since it just adds a path to check so if fixes the problem for you I'm happy with it.
