Subject: tests: run fuzzers four times in a row (#10794)
X-Git-Tag: v240~308

tests: run fuzzers four times in a row (#10794)

This should help to catch issues that are easily detectable by
bad_build_check like the one being fixed in https://github.com/systemd/systemd/pull/10793,
which would totally break the build tomorrow if I hadn't run
`helper.py check_build` manually.
