Partial revert of sys: windows: use golang.org/x/sys/windows

[thaJeztah]

reverts some changes from #4093

• preserve syscall.ENOTDIR to match os.MkDirAll
• change back parameter name to adminAndLocalSystem
• revert accidental change of permissions of parent-dir 😓 (my bad)

see the discussion on moby/moby#40645 (comment)
