Correctly detect the presence of the Adobe specific APP14 JPEG marker (bug 1140761)

Browse source 
According to the specification, http://partners.adobe.com/public/developer/en/ps/sdk/5116.DCT_Filter.pdf#G3.851943, the content of the marker segment should begin with `Adobe`, and not `Adobe\x00` as the code currently look for.

Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1140761.
Fixes the colour conversion part of issues 4090 and 5623.
