mod_firewall: Fix 'is_admin' internal dependency rule #1797 (thanks diane)
Looks like the boolean logic was inverted here. Instead, for now,
simply check if is_admin is there. It is deprecated in trunk and was
briefly removed before being brought back with a 'deprecated' warning as
part of the new roles and permissions work. Making this dependency
conditioned on the existence of the underlying function should make it
work until it actually goes away for real.
