    app: make "gegl:matting-levin" default engine of Foreground Select tool.
    
    Even though this engine is optional, we already have the code to detect
    its absence at runtime, and to fallback to "gegl:matting-global". So it
    won't be a problem even then.
    
    When the operation is present though, it definitely makes a lot more
    sense than matting global as default, because it performs a lot better
    in most cases (as far as I could see as well as others).
    
    (cherry picked from commit b52cdf4c90800452aa9717d57398ba72a5819d2a)
