[horde] Horde Groupware update 5.2.2 issue

[Peter Viskup]

Hi all,
let me share my latest finding from upgrade from 5.1.3 to 5.2.2.
We are running horde on shared hosting with suPHP and mod_security.
Unfortunately after upgrade the Horde was trying to create
horde_registry_cache_ files in /tmp where the virtualhost user don't have
permissions.
The workaround was to modify file Horde/Cache/Storage/File.php and replace
call of sys_get_temp_dir() function with the path.
