t5580: verify that alternates can be UNC paths

On Windows, UNC paths are a very convenient way to share data, and
alternates are all about sharing data.

We fixed a bug where alternates specifying UNC paths were not handled
properly, and it is high time that we add a regression test to ensure
that this bug is not reintroduced.
