Adding the following after \usepackage{tabu} should fix it:

\usepackage{ifluatex}
\makeatletter
\ifluatex
\let\tabu at message@etime\relax
\fi
\makeatother

I've attached a patch that should resolve the problem, and also another
bug that could occur if \pdfelapsedtime is not the correct primitive
(e.g. after \@ifundefined{pdfelapsedtime}{...}{...}).
