widl: Set name return value (passed by reference) in the alias case alias case in get_user_type.

[Gerald Pfeifer]

So, I admit I don't really know this code, but looking at it (triggered 
by a warning issued by GCC development versions), I noticed that this 
variable passed by reference is not initialized here.

(For reference, "typegen.c:3715:16: warning: 'uname' may be used 
uninitialized in this function" is the warning in question.)

If this is not the right fix, perhaps something else can be changed?
