avformat/yuv4mpegdec: increase header limit
Allows demuxing UHD F1000000000:33333333 fps yuvj420p files
ffmpeg (at HEAD as of now) is creating this:
```
$ ffmpeg -y -i source.265 /tmp/foo.y4m >& /dev/null
...
$ xxd /tmp/raw.y4m |less

00000060: 0a46 5241 4d45 0a82 8282 8282 8282 8282 .FRAME..........
...
```
Which cannot be parsed by the same ffmpeg decoder:
```
$ ffmpeg -i /tmp/foo.y4m /tmp/bar.y4m
...
[yuv4mpegpipe @ 0x2b69a40] Header too large.
/tmp/foo.y4m: Invalid argument
```
This is kicking the ball (per 0b1ff3265e9bdad3b4b6b97ced2f126cb3599568),
but seems to work.
