Stirling-PDF: replace dependency for v0.35.0 and add check and fix in stirling-pdf.sh (#614)

* Add check for old dependency in update_script function for stirling-pdf.sh

Checks if ocrmypdf is installed and qpdf is not; if true then removes
ocrmypdf and installs qpdf

* Replace ocrmypdf with qpdf as dependency in stirling-pdf-install.sh

As of v0.35.0, StirlingPDF now uses qpdf for OCR instead of ocrmypdf.
