avformat/flvenc: avoid 24bit timestamp truncation for FLV metadata FLV AMF tags have a 24bit field for timestamps plus an 8bit for extended timestamps. All FLV AMF tags except when we write metadata handle this correctly using the put_timestamp function. Until now when writing metadata we were only using the first 24 bits and thus the timestamp value was wraping around 4 hours 40 minutes (16,800,000 ms, max 24 bit value 16,777,216) of playback. This commit fixes this applying this same function put_timestamp for the metadata FLV tag.
