Subject: [PATCH] arm64: hyperv: make the format of 'Hyper-V: Host Build' output match x86

Currently, the following is observed on Hyper-V/ARM:

 Hyper-V: Host Build 10.0.22477.1061-1-0

This differs from similar output on x86:

 Hyper-V Host Build:20348-10.0-1-0.1138

and this is inconvenient. As x86 was the first to introduce the current
format and to not break existing tools parsing it, change the format on
ARM to match.
