#i125003# use gtest's internal tuple class for its own needs

test scripts using gtest include that gtest.h header with its dependencies.
Using the system tuple header results in slight problems on RHEL5 that can
be easily avoided by enabling gtest's internal tuple functionality. Other
platforms also benefit from the reduced header dependencies.
