Subject: [PATCH] Update ConfigLinker.php

file_exists does not work as expected but file does exist:

````
# php -r "var_dump(file_exists('./vendor/horde/horde/config/conf.php'));"
bool(false)
# ls -al ./vendor/horde/horde/config/conf.php
lrwxrwxrwx. 1 wwwrun www 27 Sep 29 09:06 ./vendor/horde/horde/config/conf.php -> ./var/config/horde/conf.php
````
