fix: remove redundant kernel version check in plymouth theme setup

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
