As mentioned in the latest pull request regarding fuzz_ppd. The current implementation of this harness contains some unhandled variable issues, e.g., ppdsize and cups_options are not properly freed when execution terminates via a return 0 condition during fuzzing.

While the overall functionality of the harness is correct, a reconstruction of this harness is required to ensure proper memory management. So that OSS-Fuzz can focus on identifying real bugs rather than surfacing false positives, which should be addressed before enabling this harness into the OSS-Fuzz fuzzing process.
