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.
