This PR addresses the issues that came up in the first round of long-term fuzzing.
We needed additional checking for parent directory symlink traversals when extracting archives along with size limits for programkind checks and ignoring invalid Yara/YAML patterns to avoid crashing the fuzzers.
Additionally, this PR cleans up more potential FD leaks and adds validation around OCI image layer sizes and fixes the UPX binary we use, among other things.
make fuzzruns cleanly with these fixes.
