When updating, write the xref table in the same format as the previous one (bug 1878916)

Browse source 
The specs are unclear about what kind of xref table format must be used.
In checking the validity of some pdfs in the preflight tool from Acrobat
we can guess that having the same format is the correct way to do.
The pdf in the mentioned bug, after having been changed, wasn't correctly
displayed in neither Chrome nor Acrobat: it's now fixed.
