ffmpeg: disable Centipede again

[kasper93]

It is not stable, there are multiple bus errors:

Step #22 - "build-check-centipede-none-x86_64":
/usr/local/bin/run_fuzzer: line 227: 172132 Bus error (core dumped) bash -c "$CMD_LINE"

Disable it for now, to let other recent changes take effect, we can revisit it later.

Fixes: 0318a94

It seems to crash on none build. See: https://oss-fuzz-build-logs.storage.googleapis.com/log-51d0cfa1-083e-4947-85d3-d8b4c2eda2a9.txt

I've actually seen the same crash on mpv https://oss-fuzz-build-logs.storage.googleapis.com/log-5a50937a-14b0-4cdb-9f59-0bdfdc77f43c.txt but it is sporadic, so I left it enabled there. In ffmpeg cases there are a lot more sanitizers and it does not pass the build.

Also I'm not sure if it is not something new, I assumed those are real issues in the code that are hit during build check, but since we are in none build check there is not sanitizer output to know. Also those are bus errors, so not your generic segmentation fault. Either way, I didn't look close, it seems to happen on mpv too from some time ago.

EDIT: Also recent build failed on OSError: [Errno 28] No space left on device instead. Since Centipede doesn't support selective extract, it is probably safer to not use it.
