Zoltan Kovacs 4843a9c74f dpx: always write the image offset 
According to the DPX file format description found at
http://www.fileformat.info/format/dpx/egff.htm the ImageElement part of
the GenericImageHeader also contains an an offset to the real image data
beside the same member that can be found in the GenericFileHeader.

Libav keeps this member empty (=0) while some applications expects it to
be filled properly. FATE test updated accordingly.
