tests: stabilize `test-clonebundles.t` on Windows
The `remote: {foo,bar}` lines were different because `echo` in MSYS uses `\r\n`.
I couldn't make it work with the previous echoing of individual lines, changing
the internal `echo` to `printf "foo\n"`, because that output as "foon". This
works on Linux and Windows, so I'm not thinking too hard about it.
