Add a guard in `get_package_lists()` to detect and skip trailing padding bytes (e.g., 0x00 or 0xFF) in the HII database blob. This prevents crashes caused by attempting to parse padding as a valid package list, which resulted in subtraction overflows.
Also ensures graceful exit if the remaining data is too short to form a valid package list header.
