fix: 修复无法执行当前目录下程序的bug (#1154)

* 更改pcb中的fs以及fNsSet结构体，以便从fs中获取pwd inode

* fmt

* 更改run-qemu.sh，为x86_64传入KERNEL_CMDLINE参数

* 提取FsStruct中的root和pwd信息

* chore(run-qemu.sh): 重构内核启动参数处理逻辑

- 优化KERNEL_CMDLINE拼接逻辑，确保参数顺序正确
- 统一使用sh -c执行QEMU命令

* refactor(mnt_namespace): 重构FsStruct使用ModeType并移除Arc包装

- 将umask类型从u32改为ModeType
- 移除path_context的Arc包装，改为直接使用RwLock
- 实现Clone trait替代自动derive
- 更新默认umask值为ModeType::S_IWUGO

* fix(run-qemu): 修改x86_64架构的init程序路径

将x86_64架构的init程序从/bin/busybox改为/bin/dragonreach
