[babl] Mostly remove BablImage from babl-fish-reference.c

[Daniel Sabo <daniels src gnome org>]

commit c6851a4859270fd9c0d16d1a955e63e2e61f35d1
Author: Daniel Sabo <DanielSabo gmail com>
Date:   Mon Oct 14 22:22:59 2013 -0700

    Mostly remove BablImage from babl-fish-reference.c
    
    There is no valid way to trigger these paths, and the BABL_IS_BABL
    call on image data produces false positives (see bug 698913).
