tdf#102928 PDF export: do recompress CMYK images
The export filter writes /DeviceRGB unconditionally, so for now don't
optimize CMYK image handling here. Though the added GraphicDescriptor
API allows supporting this natively in the export filter in the future.
(cherry picked from commit 70537c8295f1b0a0c58b061dfca6cbc9def0d65b)
