Do not intercept JVM-internal C stdlib calls
The JVM frequently calls strcmp/memcmp/..., which fills up the table of
recent compares with entries that are either duplicates of values
already reported by the bytecode instrumentation or JDK-internal strings
that are not relevant for fuzzing.
This commit adds an ignorelist to the C stdlib interceptors that filters
out calls from known JVM libraries. If the fuzz target has not yet
loaded a native library, all such callbacks are ignored, which greatly
improves fuzzer performance for string-heavy targets. E.g.,
JsonSanitizerDenylistFuzzer takes < 1 million runs now when it used to
take over 3 million.
