fix: 在 gpustack prerun 中启用 gpustack-server s6 服务

- gpustack/utils/s6_services.py 新增 gpustack_server_services 定义
- gpustack/cmd/prerun.py 在 determine_enabled_services 中加入 gpustack-server
- gpustack/cmd/prerun.py 在 determine_dependency_services 中加入依赖声明
- 确保 server/both 角色下 gpustack-server 会被 s6-overlay 自动启动
