[folks] build: Drop check for libvaladoc

    build: Drop check for libvaladoc
    
    We don’t use the library, we just use the valadoc binary, so there’s no
    point in checking for the library. It means our build keeps breaking
    whenever libvaladoc changes the naming of its .pc file (which happens
    once each stable release cycle).
