fix: remove Install sections from systemd sound services

1. Removed [Install] sections from both deepin-login-sound.service and
deepin-shutdown-sound.service
2. These services are meant to be triggered manually rather than being
enabled/started at boot
3. The WantedBy directives were unnecessary since these are one-shot
services
4. Improves system startup performance by not loading unnecessary
services

fix: 从 systemd 声音服务中移除 Install 部分

1. 从 deepin-login-sound.service 和 deepin-shutdown-sound.service 中移除
了 [Install] 部分
2. 这些服务设计为手动触发而非在启动时自动启用/运行
3. WantedBy 指令对于一次性服务来说是不必要的
4. 通过不加载不必要的服务来提高系统启动性能
