It could technically be built, but it was missing the qt4 frontend because
newer poppler versions had removed it from its source entirely.

Nobody else uses poppler-qt4 in Guix - otherwise the client would have noticed
that it did not work at all.

I just needed a PDF differ which requires poppler-qt4, so I fixed poppler-qt4.
