fix: 解决没有关机音效的问题

[fly602]

因为用 Requisite= 是“硬依赖”。如果系统上没激活 sound.target（很多环境确实不会激活它），这个服务就不会在开机被拉起，结果就是 enabled 但一直 inactive (dead)

Log: 去掉Requisite，改成Wants
PMS: BUG-315787
Influence: 系统音效

Summary by Sourcery

Bug Fixes:

• Replace Requisite=sound.target with Wants=sound.target in deepin-shutdown-sound.service to prevent the service from staying inactive in environments without sound.target

我来分析这个systemd服务文件的变更：

1. 变更内容：

• 移除了Requisite=的依赖项
• 新增了Wants=的依赖项
• 保留了After=和Before=的配置

2. 改进意见：

a) 语法逻辑：

• 原代码中Requisite=sound.target local-fs.target的写法有误，因为Requisite指令只能有一个单元作为依赖
• 修改后的代码将依赖关系改为Wants=是正确的，因为Wants允许多个依赖项

b) 代码质量：

• 建议明确指定服务的行为意图，考虑添加Description的更详细描述
• 建议添加DefaultDependencies=yes以明确默认依赖关系的行为

c) 代码性能：

• 使用Wants=而不是Requires是合理的，因为关机声音播放不是关键系统功能
• 保留After=确保服务在依赖项之后启动，这是正确的

d) 代码安全：

• 配置看起来是安全的，没有明显的安全隐患
• 建议添加Type=明确指定服务类型，例如Type=simple

3. 建议的改进版本：

[Unit]
Description=Deepin shutdown sound service
DefaultDependencies=yes
Wants=sound.target local-fs.target
After=sound.target local-fs.target
Conflicts=shutdown.target
Before=shutdown.target
Type=simple

这些改进使得服务文件更加清晰和完整，同时保持了原有的功能意图。主要改进包括：

1. 修复了依赖关系的语法错误
2. 添加了更详细的描述
3. 明确了默认依赖行为
4. 指定了服务类型
5. 保持了原有的启动顺序和冲突关系
