    build: Modify how we define the GSettings schemas
    
    These changes are needed so that the 'tracker-miners' project can make
    use of the 'tracker' settings schemas when build with the
    `tracker=subproject` option.  There should be no change to funtionality.
    
    This is related to https://gitlab.gnome.org/GNOME/tracker/issues/24
