    avcodec/cbs_av1: don't try to write a Redundant Frame Header as a normal one
    
    Section 6.8.1 of the AV1 specification states:
    
    "If obu_type is equal to OBU_REDUNDANT_FRAME_HEADER, it is a requirement of
    bitstream conformance that SeenFrameHeader is equal to 1."
    
    Leave the existing behavior for reading scenarios as such a file may still
    be readable.
