Added verbaige for systems that don't specifically use /etc/yum.conf in the case of looking for "gpgcheck=1".
Many consider using /etc/yum.conf for all repo information to be an odler, and depreciated method.
Most systems use /etc/yum.repos.d/(reponame).repo method, of which the check didn't have an explanation for.
Added this "/etc/yum.repos.d/(reponame).repo" text, and retested rule. <PASS>
