Updated qpdf packages fix security vulnerabilities

Updated qpdf packages fix security vulnerabilities:

  1. Stack overflow due to endless recursion in QPDFTokenizer::resolveLiteral()
  2. Another stack overflow / endless recursion in QPDFWriter::enqueueObject()
  3. Stack out of bounds read in iterate_rc4()
  4. heap out of bounds read (large) in Pl_Buffer::write
  5. Hang due to a pdf xref loop:

Also, the libjpeg package has been patched to provide pkgconfig files, so that cups-filters could be rebuilt against this qpdf update.
