Set permissions to a SID not to the group Users, fixing a bug that is triggered

on localized versions of Windows.
----
Non-English versions of Windows do not have a Users group; instead they use a
localized group name. As a result, when installing I2P on a non-English Windows
box, the installer will show an error when trying to run the fixperms.bat
script.

Using the SID will work with any localized Windows. SID list @
