[gdk-pixbuf] tests: Add pixbuf-fail test

[Benjamin Otte <otte src gnome org>]

commit 4a78a60d34e1a1b2f6651df26ba8d37394328c6e

    tests: Add pixbuf-fail test
    
    pixbuf-fail goes into test-images/fail and loads all the images in
    there, checking that a proper error happens during loading.
    
    This is useful for invalid images that cause crashes: Put them in there
    after they are fixed.
