Disable zip_iterator test with std::tuple on gcc 4.4.

Browse Source 
libstdc++ from gcc 4.4 has a broken std::tuple that fails to compile
a constructor from a compatible tuple:

/usr/include/c++/4.4/tuple: In constructor 'std::_Head_base<_Idx, _Head, false>::_Head_base(_UHead&&) [with _UHead = std::_Head_base<0ul, const int&, false>, long unsigned int _Idx = 0ul, _Head = int]':
/usr/include/c++/4.4/tuple:179:   instantiated from 'std::_Tuple_impl<_Idx, _Head, _Tail ...>::_Tuple_impl(std::_Tuple_impl<_Idx, _UElements ...>&&) [with _UElements = const int&, double&, long unsigned int _Idx = 0ul, _Head = int, _Tail = double]'
/usr/include/c++/4.4/tuple:338:   instantiated from 'std::tuple<_T1, _T2>::tuple(std::tuple<_U1, _U2>&&) [with _U1 = const int&, _U2 = double&, _T1 = int, _T2 = double]'
libs/iterator/test/detail/zip_iterator_test_original.ipp:137:   instantiated from here
/usr/include/c++/4.4/tuple:94: error: cannot convert 'std::_Head_base<0ul, const int&, false>' to 'int' in initialization
