Some permissions corrections here. Also needs re-vendor of go-winio.

 - Create the layer folder directory as standard, not with SDDL. It will inherit permissions from the data-root correctly.
 - Apply the VM Group SID access to layer.vhd

Permissions after this changes

Data root:

```
PS C:\> icacls test
test BUILTIN\Administrators:(OI)(CI)(F)
     NT AUTHORITY\SYSTEM:(OI)(CI)(F)
```

lcow subdirectory under dataroot
```
PS C:\> icacls test\lcow
test\lcow BUILTIN\Administrators:(I)(OI)(CI)(F)
          NT AUTHORITY\SYSTEM:(I)(OI)(CI)(F)
```

layer.vhd in a layer folder for LCOW
```
.\test\lcow\c33923d21c9621fea2f990a8778f469ecdbdc57fd9ca682565d1fa86fadd5d95\layer.vhd NT VIRTUAL MACHINE\Virtual Machines:(R)
                                                                                       BUILTIN\Administrators:(I)(F)
                                                                                       NT AUTHORITY\SYSTEM:(I)(F)
```

And showing working
