[SERVICES] Assign a World identity authority for Everyone SID, not Null authority

Browse Source 
The current code allocates memory and initializes the Everyone "World" security identifier but with a Null authority identifier. This is utterly wrong on so many levels, more so partly because a Null authority identifier is 0 so after the Everyone SID is initialized, it is actually initialized as S-1-0-0 instead of S-1-1-0.
