[libsigcplusplus/variadic_mem_fun2] bound_mem_functor: Remove constructor that takes pointer.

    bound_mem_functor: Remove constructor that takes pointer.
    
    Leaving just the constructor that takes the object by reference.
    This is not a class that application code would use directly,
    so there seems no need for the convenience.
