evas: Fix evas gif image loader for libgif version 5

Because arc doesn't like me much at the moment here's a simple patch to
fix the gif loader for the latest libgif version. DGifOpen now takes a
error param as its final argument, if the param is not NULL it will
return a error code if it fails. Similar to another patch i sent a few
months back. The patch has been tested on OBS for old and new versions.
