Update ctests to reflect inputenc changes

There were changes to inputenc and luainputenc that are now
released in Tex Live 2014 that affect several exports. Some
exports that produced good PDFs now fail. Others that produced
incorrect PDFs (with gibberish) now correctly fail. Several
IEEEtran-* exports failed before and now export correct PDFs.
