x86/hyperv: Output host build info as normal Windows version number

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.
