Kefu Chai c36945dea2 tasks: include used headers ...

when compiling with Clang-18 + libstdc++-13, the tree fails to build:
```
/home/kefu/dev/scylladb/tasks/task_manager.hh:45:36: error: no template named 'list' in namespace 'std'
   45 |     using foreign_task_list = std::list<foreign_task_ptr>;
      |                               ~~~~~^
```
so let's include the used header
