obsolete: make sure windows tests pass when stat() is given a URL

This is a temporary fix for an issue that's only visible on windows, but exists
on other platforms as well.

The issue is if we're trying to use obsstore from a remote peer and that peer
is a static HTTP repo, vfs tries to os.stat() a remote file using a URL to that
file (e.g. http://localhost/repo/.hg/store/obsstore). The next patch in this
series makes branchcache obsolescence-aware, so in certain situations exchange
process will try os.stat()ing a URL. On windows this will produce an OSError
that is not ENOENT, but EINVAL instead (because of `:` symbol, for example).
