cdoecs: av1: Copy system_frame_number in duplicate_picture

Browse source 
The system_frame_number is notably used by V4L2 decoder as a unique
indentifier for the frame that was decoded. This value is used to tell driver
which frame to reference, as V4L2 does not have an efficient mechanism to
otherwise pass back the frames.

For this reason, and because it is more ligical, copy the original
system_frame_number into the duplicate picture instead of using the current
frame.
