tools/target_dec_fuzzer: Disable MB debug after a few iterations
This debug code can be quite slow on constructed streams Fixes: Timeout Fixes: 38907/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_H264_fuzzer-6334628852531200 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
