John Beard 55370e7520 QA: BOOST_CHECK to _TEST in some KiMath tests 
This tells you the arguments when it fails.

BOOST_TEST is available in all our Boost.Test version.
Even if you didn't use it, these calls should have been
BOOST_TEST_EQUAL(A, B) which also tells you the
arguments on a test failure.
