    fate/cbs: add h264_metadata BSF test exercising SEI handling

    Test cbs_sei code paths through the user-facing h264_metadata BSF
    interface, as suggested by jkqxz, rather than with direct unit tests
    against the unstable internal CBS API.

    The test exercises sei_user_data (SEI_TYPE_USER_DATA_UNREGISTERED),
    AUD NAL unit insertion, and display_orientation SEI in a single
    invocation.
