x86/hyperv: Output host build info as normal Windows version number
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2060708
Hyper-V provides host version number information that is output in
text form by a Linux guest when it boots. For whatever reason, the
formatting has historically been non-standard. Change it to output
in normal Windows version format for better readability.
Similar code for ARM64 guests already outputs in normal Windows
version format.
