在 Ubuntu 24.04 (noble) 上的 jetson-inference 构建失败 — jetson-utils 子模块不一致

cmake 配置在构建 ZZTERM18ZZ 绑定时失败，出现了几个较旧的已解决问题（#538、#1228、#1799、#1730）中常见的重复目标签名：
-- found ZZTERM19ZZ version: 3.12 (3.12.3)

-- detecting ZZTERM27ZZ 3.7...构建尝试使用第二个不同请求的 ZZTERM28ZZ 版本 ("detecting ZZTERM29ZZ 3.7...")，紧跟着成功通过 3.12 版本 — 这个问题的历史实例都遵循相同的模式：PYTHON_BINDING_VERSIONS 列表包含多个条目，其中多个条目都解析为主机上的同一实现，导致 CMake 目标重复出现。
