Fix centipede exceptions

[jonathanmetzman]

It's exceptioning all over the place in oss-fuzz.
#4040 seems broken becuase it's having oss-fuzz run fuzzers for builds that aren't happening. I think projects aren't being built with centipede by default on oss-fuzz.

See gs://clusterfuzz-builds-centipede/hwloc/ or fftw3.
I think we should talk about whether we want to force centipede on new projects at this point, so I'm not sure the right move is to enable the builds on the oss-fuzz side. I imagine this will cause many build fails.
But for now, since builds on the oss-fuzz side are opt-in, making this opt-out is not helping anyone. I will revert for now. Sorry, but I want to see a more accurate picture of the health of oss-fuzz before I go on vacation.

Skia noticed this caused weird behavior where the old build (from April 2023) was used https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=71292 causing bugs to be filed for extremely old builds.

About 50 bugs were opened in the past few days for centipede, 17 of which are security bugs (usually there none)
I think all of these are suspect.
