Fixed a warning in SecurityClass.inc

In SecurityClass.inc it is possible to get the warnings:
warning: Invalid argument supplied for foreach() in /var/www/sites/all/modules/fedora_repository/SecurityClass.inc on line 84.
warning: Invalid argument supplied for foreach() in /var/www/sites/all/modules/fedora_repository/SecurityClass.inc on line 89.

These happen when the XACML policy doesn't contain any roles or users.
