image/cache: Require Major and Minor match for Windows OSVersion

Browse source 
The platform comparison was backported from the branch that vendors
containerd 1.7.

In this branch the vendored containerd version is older and doesn't have
the same comparison logic for Windows specific OSVersion.

Require both major and minor components of Windows OSVersion to match.
