    build: Add tracker-sparql-2.0 to checks
    
    No code changes required, it is expected to remain API compatible
    with the current usage in folks. The TrackerSparqlBuilder API is not
    recommended for new development (superseded by TrackerResource), but
    it will be just marked as deprecated, not removed.
