test(lmbench): 添加 UDP 和 Unix socket 性能测试脚本

添加 UDP 协议和 Unix domain socket 的性能测试脚本：

UDP 测试：
- udp_loopback_lat.sh: UDP loopback 延迟测试
- udp_virtio_lat.sh: UDP virtio 延迟测试

Unix domain socket 测试：
- unix_bw.sh: Unix socket 带宽测试
- unix_lat.sh: Unix socket 延迟测试
- unix_connect_lat.sh: Unix socket 连接延迟测试

UDP loopback 和 Unix socket 连接测试包含服务端自动管理。
UDP virtio 测试需要在 10.0.2.15 运行服务端。
