Man page fix for unlang

[Chris Moules]

There is a logic error in the unlang man page.

I was just reading this:
---
        Operators
               The operator used to assign the value of the attribute may be one of the following, with the given meaning.
               =      Add the attribute to the list, if and only if an attribute of the same name is already present in that list.
               :=     Add  the  attribute  to the list.  If any attribute of the same name is already present in that list, its
value is replaced with the value of the current attribute.
---

I was fairly sure that the '=' operator only assigned if the value is NOT set. I checked the docs on the wiki
(http://wiki.freeradius.org/Operators) which states this.

Below a quick patch.

Chris
