vcl PDF export: fix re-exporting PDF images for dict obj resource sub-keys

Re-exporting PDF images works by tokenizing the PDF image, identifying
which PDF object is the page object and then copying that over to the
PDF output, together with the dependencies of that object.

This involves copying the resources of the page object. Previously we
assumed that the sub-keys of the resources are always inline
dictionaries, but the bugdoc shows that they can be references as well,
which point to dictionary objects, so add support for this scenario.
