Limin Wang f3568a33c9 avformat/mpegtsenc: use total_size instead of avio_tell() 
avio_tell() fails to get the amount of data written so far when the
underlying IO context is flushed to segments.

Please test with below command:
$ ./ffmpeg  -f lavfi -i testsrc=duration=100:size=vga -c:v libx264 -x264opts \
  nal-hrd=cbr:force-cfr=1 -b:v 500k -minrate 500k -maxrate 500k -bufsize 500k \
  -f hls -hls_time 10  -hls_ts_options "muxrate=2000000" test%d.ts

$ du -h test*.ts
Before:
2.4M    test00.ts
4.8M    test11.ts
7.2M    test22.ts
9.6M    test33.ts
12M     test44.ts
...

After apply the patch:
 2.4M   test00.ts
 2.4M   test11.ts
 2.4M   test22.ts
 2.4M   test33.ts
 2.4M   test44.ts
