    libtracker-sparql: Fix bad serialization of date/time values
    
    TrackerResource was creating bad SPARQL & Turtle from GDateTime values.
    
    If you saw this...
    
        GDBus.Error:org.freedesktop.Tracker1.SparqlError.Type: Not a ISO
        8601 date string. Allowed form is [-]CCYY-MM-DDThh:mm:ss[Z|(+|-)hh:mm]
    
    ...it's because in the arguments for g_date_time_format() I confused %S
    (seconds since the last minute) with %s (seconds since 1st January
    1970). That's a lot of extra seconds.
