Fix building tiflash using clang-17 docker image (#2712)

Try to build tiflash using clang-17 docker image
https://github.com/pingcap/tiflash/pull/8537

But the CI will run into errors like
https://ci.pingcap.net/job/tiflash-build-common/33843/console
```
[2023-12-30T15:06:42.887Z] + git log -1 --format=%H
[2023-12-30T15:06:42.887Z] fatal: detected dubious ownership in repository at '/home/jenkins/agent/workspace/tiflash-build-common/tiflash/contrib/tiflash-proxy'

23:16:59  CMake Error at dbms/cmake/version.cmake:20 (execute_process):

23:16:59  
23:16:59  Call Stack (most recent call first):
23:16:59    dbms/CMakeLists.txt:25 (include)
```

Add git safe.directory to workaround the errors. After these changes,
the pipeline can build tiflash with clang-17 successfully:
