[JBIG2] Ensure that the decodeInteger function returns valid integers (issue 15942)

Browse source 
The JBIG2 images in this PDF document are corrupt enough that even Adobe Reader warns about it when opening the file.
*Please note:* I don't really know the JBIG2 image format at all, however from a very brief look at the specification it seems that integers should be 32-bit.
