test-clonebundles: conditionalize output for Windows

This was the fallout from 9d6031df42c8 (on stable).  Now that individual lines
can be conditionalized, it seems better to be explicit, rather than mash all of
this into one regex.  "getaddrinfo failed" was added in 4e566f513fd8 to support
Windows.
