    gegl: Allow overriding the number of threads
    
    A subsequent commit will use gegl:path to create images that will be
    used as input data for testing. It turns out that, for hitherto
    unknown reasons, using multiple threads causes minor disturbances in
    gegl:path's output which interferes with the tests. Therefore, it is
    useful to override the number of threads used by GEGL for affected
    tests where the multi-threading isn't part of the code that is being
    tested.
    
    Since gegl_init reads the GEGL_THREADS environment variable, it has to
    be called later so that it can override the default GEGL
    configuration.
