    config_kde: Decide whether to build the module based only on WITH_KDE.

    kreadconfig/kreadconfig5 are runtime dependencies only. As such, there
    should not be a build-time dependency on those in CMake at all. In other
    words, building without those binaries works perfectly fine, and they
    are only required when running libproxy.

    Make the KDE config module optional again.

    This is a follow-up to bd9bf72 ("Add generic KDE config module"): make
    it possible for distributions to not build the KDE config module at all,
    even if it does not have any dependencies on Qt/KDE/KF5.
