Changed call in ClassMapAutoloader to preserve original behaviour

In PHP8 the third param of array_walk ($userdata) is automatically
passed by value thus calling a function that expects pass by reference
as the third param is not possible.
Simply changing the array_walk to a foreach loop allows us to fulfill
the pass by reference signature.
