Remove _Safe_container _IsCxx11AllocatorAware template parameter

[François Dumont]

Hi

    _Safe_container _IsCxx11AllocatorAware template allocator is only 
used if C++11 Abi is not used so I simplified it.

    * include/debug/safe_container.h [_GLIBCXX_USE_CXX11_ABI]
    (_Safe_container<>): Remove _IsCxx11AllocatorAware template parameter.
    * include/debug/string: Adapt.

    Tested under Linux x86_64 with debug mode and active C++11 Abi.
