[boost] Python / extract.cpp: disable warning

This warning in the extract test case should also be disabled for Intel 8:

..\libs\python\test\extract.cpp(59): warning #473: returning reference 
to local temporary
       return extract<std::string const&>(x);
              ^

BTW, is this a compiler defect?
