[FFmpeg-devel] [PATCH 5/6] tools/target_dec_fuzzer: Adjust threshold for G2M

[Michael Niedermayer]

G2M allows large images from small input and also reallocates
multiple buffers on any resolution change.

Fixes: Timeout (22sec -> 5sec)
Fixes: 18022/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G2M_fuzzer-5089192530411520
