    build: Always enable the pdf backend
    
    Since Evince 42.0 we became more aggressive to bump poppler's version,
    and let users use the improvements in PDF rendering.
    
    Additionally, pdf is likely the most used file format. It makes sense
    to attempt to enable it by default, and let the user force to disable
    it if they please.
