There are two specific WQL queries we're using to get either a list of
virtual machines or the hypervisor host itself from Msvm_ComputerSystem.
Those queries rely on filtering results based on the "Description"
field. Since the "Description" field is locale sensitive, the queries
will fail if the Windows host is using a language pack. While the WSMAN
spec allows the client to set the requested locale (and it is supported
since openwsman 2.6.x), the Windows WinRM service does not respect this
setting: it returns non-English strings despite the WSMAN request
properly setting the locale to 'en-US'. Therefore, this patch changes
the WQL query to make use of the "__SERVER" field to stop relying on
English strings in queries and side step the issue.
