fix: remove redundant kernel version check in plymouth theme setup

[robertkill]

The change removes an unnecessary kernel version check when setting the Plymouth theme. The check was redundant because the subsequent update- initramfs command already handles all kernel versions with the "-k all" parameter. This simplifies the code and removes an unnecessary system call.

Influence:

1. Verify Plymouth theme changes still work correctly
2. Check that initramfs updates properly for all kernel versions
3. Test system boot process with different themes

fix: 移除Plymouth主题设置中多余的内核版本检查

该变更移除了设置Plymouth主题时不必要的内核版本检查。由于后续的update-
initramfs命令已经通过"-k all"参数处理所有内核版本，这个检查是多余的。这
简化了代码并移除了不必要的系统调用。

Influence:

1. 验证Plymouth主题更改仍能正常工作
2. 检查initramfs是否能为所有内核版本正确更新
3. 使用不同主题测试系统启动过程

Summary by Sourcery

Enhancements:

• Remove exec.Command("uname", "-r") call from setPlymouthTheme to eliminate an unnecessary system call and redundant version check

Reviewer's Guide

This PR streamlines the Plymouth theme setup by removing the manual kernel version check and relying solely on update-initramfs -k all for all kernels, and updates the Debian changelog to reflect this change.

    %% The setPlymouthTheme method no longer performs a kernel version check before calling update-initramfs.

代码审查意见：

1. 代码注释和文档：

   • 在plymouth.go文件中，移除的代码块没有相应的注释说明为什么移除。建议添加注释说明为什么不再需要获取内核版本，以便其他开发者理解这一变更的背景。

2. 错误处理：

   • 在setPlymouthTheme函数中，当执行exec.Command("uname", "-r")命令失败时，错误信息只包含err，没有包含具体的命令输出。建议在错误信息中包含命令的输出，以便更好地诊断问题。

3. 代码质量：

   • 移除的代码块中，kernel, err := exec.Command("uname", "-r").CombinedOutput()这行代码被移除，但没有相应的逻辑替代。如果这个命令的输出不再需要，应该确保整个功能逻辑是完整的，并且相关的逻辑已经更新。

4. 性能：

   • 没有明显的性能问题，但是建议检查exec.Command的执行频率，如果频繁执行，可能会影响性能，可以考虑缓存结果或者优化执行逻辑。

5. 安全性：

   • 使用exec.Command执行外部命令时，需要确保命令的参数是安全的，以防止命令注入攻击。在这个例子中，"update-initramfs", "-u", "-k", "all"是固定的参数，应该没有安全问题。

6. 日志记录：

   • 如果移除的代码块中的命令执行失败，建议在日志中记录详细的错误信息，以便于问题的追踪和调试。

综上所述，建议在移除代码块时添加相应的注释，并确保相关的逻辑已经更新，以保持代码的完整性和可维护性。同时，对于错误处理和日志记录，应该更加详细，以便于问题的诊断和修复。
