Title: Added definitions on AIX for internal time.

A declaration of timegm was not found for AIX resulting in a compilation failure. Both #define BOOST_CHRONO_INTERNAL_TIMEGM and #define BOOST_CHRONO_INTERNAL_GMTIME do not take into account the AIX platform even though in the AIX platform it works the same way in all the previously listed platforms.
