[test] Update mime-data jpeg reference data.

<adrianj> ickle_: If we are going to use a different image for jpeg in
mime-data maybe we could create a jpg that contains the text "jpeg". That
way when support for the other image formats is added the mime-data test
could have one image for each type with each image and it is easy to see
that each image is the correct one.
