    win32: Fix #4286 about the restore of a volume root directory with the hidden & system attributes

    - Detect root directories like C:\ or C:\mount_point
      and setup st_rdev=WIN32_ROOT_POINT to tell restore to not restore
      the hidden and system attributes
    - Be aware that there is 2 different "directories" (1) the parent
      directory like c:\mount_point and (2) the root directory of the volume
      that your are attaching to the parent. The attributes that you see is
      the attribute of (1) but for drive letters, their is no (1) then
      you see always (2) (that are hidden and system).
      When VSS snapshot is used
