Make the EOI check in TiffReader.getJpegRawImageData()
only get performed when the strict flag is set,
as some images out in the wild seem to have thumbnails
without a valid EOI.

IMAGING-99 was the reason that EOI check was needed.
However testing the IMAGING-99 image with the section
commented out still works, so the EOI check wasn't 
what fixed IMAGING-99 

Jira issue key: IMAGING-108.
