Windows 10 Rule V-63373 fails to apply settings to system drive

[mapresto]

Describe the bug
Attempting to run the rules for V-63373 on Windows 10 brings up the following errors in the job:
Exception calling "RemoveAccessRuleAll" with "1" argument(s): "Some or all identity references could not be
translated."
+ CategoryInfo : NotSpecified: (:) [], CimException
+ FullyQualifiedErrorId : IdentityNotMappedException
+ PSComputerName : Win10Test

To Reproduce
Create a small mof with the 63373.a rules only and attempt to apply it to a system.

Expected behavior
Completed jobs and ACE's applied to the system drive. As of right now, jt is attempting to apply to %SystemDrive%. This corresponds to C: on most systems which does not interpret correctly in PowerShell. Inside the mof, it should be %SystemDrive%\ in order to properly label it as the root of the C drive. The Server 2012 STIGs properly adds the escaped backslash to the mof.

Comparing WindowsServer-2012R2-DC-2.16.xml to WindowsClient-10-1.16.xml I see this difference:

WindowsServer-2012R2-DC-2.16.xml has <Path>%SystemDrive%\</Path>
WindowsClient-10-1.16.xml has <Path>%SystemDrive%</Path>

The \ is added on the 2012R2-DC STIG in the xml.
