    build: Compile GSettings schemas after install
    
    This isn't needed in the common case of distro package builds, as the
    distro package will already provide a hook. However, our README.md
    tells developers to install into a prefix like ~/opt/tracker, and
    that is broken by default because GLib will complain that none of the
    settings schemas are installed.
