Could you do it without reflection, then? I don't think so.
Thus, I think your "use case" is broken by design.

If you need to call Parent::whoami with the Child scope,
maybe you shouldn't override the method in Child class at all.

If this kind of functionality is generally needed,
maybe it could be borrowed from C++:
obj_b->A::whoami();
Translated to PHP/Reflection:
new ReflectionMethod("B", "A::whoami")->invoke();
