vcl: re-exporting broken pdfs -> empty pages
Certain pdf documents when loaded in LO_IMPORT_USE_PDFIUM=1 mode even if
pdf-version < v1.6 sometimes has missing objects referred by other
objects for determing its stream length for instance. As a result
parsing fails and results in a pdf with empty pages. A round trip
through pdfium and exporting to v1.6 seems to cure the issue. Possibly
it does some repairing work to determine the length of the stream in a
independent pass through the file.
