clar: mark `cl_git_thread_check()` as inline The function `cl_git_thread_check()` is defined as static. As the function is defined in a header file which is included by our tests, this can result in warnings for every test file where `cl_git_thread_check` is never used. Fix the issue by marking it as inline instead.
