According to this source file they are reading into kernel32.dll version
resource. This data does not change when you switch reported version for your
wineprefix. In order to match one to another we'll need some magic to
dynamically adjust version blobs, after system modules are loaded. Right now
this won't work obviously. I have no idea what was the motivation to ignore
what GetVersionEx() returns, and use proper manifests with compatibility
sections.
