image/jpeg: decoding fails when image ends with "\xff\x00\xff\xd9"

[nigeltao]

The person who sent me the attached JPEG says that it's viewable from C (presumably
libjpeg). Go fails with "unknown marker" because the "\xff\x00" is
interpreted as a marker instead of a 0 byte for the Huffman decoder. I'm not sure yet if
the image is actually spec-compliant or if libjpeg is being liberal in what it accepts.
