Bug 1533589: [win64-aarch64] Simplify logic about unpacking builds in update-verify; r=sfraser

We always pass in the platform formated as an update platform. Since the only
variation in formats is between major platforms, be liberal in parsing
platforms, when selecting which unpack logic to use. This makes win64-aarch64
support fall out automatically.
