Restrict the object types that FPDF_CopyViewerPreferences() copies.

Prevent FPDF_CopyViewerPreferences() from copying bad data. In the
malformed PDF in the bug, the /ViewerPreferences pointed to the catalog,
so FPDF_CopyViewerPreferences() tried to copy the entire (large) PDF
without using references.
