test failure with gdk-pixbuf 2.38.1

[kenhys]

Problem

./test/run-test.sh fails with gdk-pixbuf 2.38.1+dfsg-1.

Even though changed to use gdk_pixbuf_read_pixel_bytes in expected, the result of gcut_object_inspect(G_OBJECT(pixbuf1)) is still different. It seems that pixel-bytes are newly allocated implicitly.

Actual

(no modification in test/gdkcutter-pixbuf/test-gdkcut-pixbuf.c)
