Whenever we want to tell our payload about a path, we limit ourselves to a reasonable amount of characters. So far we only passed in device names - exceeding 16 chars was unlikely there. However by now we also pass real file path information, so let's increase the limit to 32 characters. That way common paths like "boot/efi/bootaa64.efi" fit just fine.
