Fix broken LaTeX code generated by doxygen. Changing package

fancyhdr's \footrulewidth has always been documented using
\renewcommand (as opposed to \setlength), and the LaTeX from teTeX 2.x
barfs about it otherwise.

This is merely a stop-gap measure until the maintainer finds the time
to upgrade the doxygen port to a current version.
