tests: c++: fix symbol lookup issue
Sun C 5.13 SunOS_sparc 2014/10/20 reports errors on tests 430-432.
Reported by Dennis Clarke.
<http://lists.gnu.org/archive/html/bug-bison/2015-01/msg00087.html>
* tests/c++.at (Variants): Be sure to emit operator<< before using it:
use "%code top" rather than "%code".
Prefer std::vector to std::list.
Do not define anything in std::, to avoid undefined behavior.
