What I did in Fedora is to add a post install action like this:

%post
# Copy default rules into place on new installation
if [ ! -e /etc/audit/audit.rules ] ; then
        cp /etc/audit/rules.d/audit.rules /etc/audit/audit.rules
fi

This way if its a new install, you get a copy of the rules and if there are 
any previously existing rules, they are not overwritten.
