Widen the //go:build constraints on every shared usbip file from
"linux || (darwin && cgo)" to also include "windows", narrow
register_stub.go to exclude windows, and add backendIDWindowsVBoxUSB
so the upcoming Windows export host can stamp its snapshots.
No behavior change on darwin/linux: the existing platform-specific
files keep their narrower tags, and the windows build still lacks the
newPlatform{Export,Import}Host functions until the next commit.
