fix: remove deprecated Boost.System component from CMake

[hillwoodroc]

Boost.System is header-only in newer Boost versions (e.g. 1.89) and no longer provides boost_systemConfig.cmake or libboost_system.

Keeping find_package(Boost COMPONENTS system) causes configuration errors because the component no longer exists. Switching to a plain find_package(Boost REQUIRED) restores compatibility and works on all modern Boost installations.

Log: This fix updates both daemon and searcher CMakeLists accordingly. Also fixes missing newline at end of file in searcher CMakeLists.txt.

Summary by Sourcery

Update CMake Boost discovery to avoid requiring the deprecated Boost.System component.

Build:

• Relax Boost CMake dependency from Boost COMPONENTS system to a generic Boost REQUIRED in daemon and searcher targets to support newer header-only Boost.System.
• Fix formatting by ensuring the searcher CMakeLists.txt ends with a newline.

Hi @hillwoodroc. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@hillwoodroc 你好, 目前该代码需要支持低版本的 boost (1.67), 看如何增加下兼容性
如 find_package(Boost OPTIONAL_COMPONENTS system)

更新了 patch，保留了对旧版 boost 的支持。

使用 Boost_VERSION 与版本字符串比较不起作用, 可以考虑使用 Boost_VERSION_STRING 或者版本整数

更新提交，用 Boost_VERSION_STRING 代替。版本整数似乎在 1.89 上有问题。
