xmlsecurity: fix the PDF incremental update's cross-references table
The VCL pdf export writes a space after the in-use entry, and turns out
Adobe Acrobat starts to "repair" the file if there is no such space.
Which means the signature is validated against the repaired document,
resulting in a "The signature byte range is invalid" error message,
hiding the root cause.
Not that ISO-32000 7.5.4 "Cross-References Table" would mention the need
for such whitespace at the end of the lines.
