    codecparsers: h264: fix rbsp_more_data() implementation.

    Account for trailing zero bits when checking for rbsp_more_data().

    In particular, fix an hypothetical stream whereby rbsp_more_data()
    is called in the following conditions for PPS header: NalReader
    reached position 20, 12 bits are remaining and trailing data at
    current byte position is c8 00.

    rbsp_more_data() used to return TRUE whereas it should obviously
    return FALSE because x8 00 represents a valid rbsp_trailing_bits()
    structure.
