    libstdc++: Initialize base in test allocator's constructor
    
    This fixes a warning from one of the test allocators:
    warning: base class 'class std::allocator<__gnu_test::copy_tracker>' should 
be explicitly initialized in the copy constructor [-Wextra]
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/util/testsuite_allocator.h (tracker_allocator):
            Initialize base class in copy constructor.
    
    (cherry picked from commit e2fb245b07f489ed5bfd9a945e0053b4a3211245)
