Explicitly match .cargo_vcs_info.json, note windows difference in test

The package_verbose test has different output on windows, and from
that output I can only conclude that on windows, and windows only,
cargo is failing to find the parent repo. Note that difference. As the
new .cargo_vcs_info.json of PR #5786 is a best effort, informative
only, this independent problem on windows seems acceptable to the
feature.
