[AMBER-Developers] CUDA Conformance Test not deterministic

This test appears to be ever so slightly nondeterministic. About 1 in 4
runs on TOT is showing this tiny difference. I suspect is because DPFP
energy accumulation is not quite deterministic. Which is preferable here?
Increasing the tolerance by a factor 2 or ignoring the test?
