Modified pipeline to fix regression and return the proper error code if
we did not produce a PDF/A as expected. The wrapper forces the output
to be PDF 1.3 which is not PDF/A compliant.
The funny thing is that in some cases JHOVE incorrectly states that a
file is PDF/A-1b compliant, well formed and valid, even when it is not
according to Acrobat XI and is missing the PDF/A metadata marker, as
far as I can tell. JHOVE may not be as beneficial as hoped.
