The fuzz test runner does not add the UBSan suppressions when fetching the harness list. We can observe this in CI as lots of UBSan errors prior to the harnesses actually executing: https://api.cirrus-ci.com/v1/task/5678606140047360/logs/ci.log

To fix this we simply apply the usual fuzz env variables (that apply the suppressions) when fetching the harness list as well.

I was running the fuzz tests locally and noticed same behavior, I can confirm that 738a537 suppress the warnings.
