Rare coverage ID sync failures

See original GitHub issue

As reported by ClusterFuzz, coverage IDs can become desynchronized between child processes in fork mode. I attached a log obtained from the ValidJsonFuzzer fuzzer of the json-sanitizer project.

@sebastianpoeplau Could you review https://github.com/CodeIntelligenceTesting/jazzer/blob/main/agent/src/main/java/com/code_intelligence/jazzer/agent/CoverageIdStrategy.kt again for potential synchronization issues? Any idea on how to improve logging of these cases further would also be helpful.
