v2remotes-hg: bugfix for fetching non local remotes

> 6796d49 introduced a bug by making shared_path == ".git/hg' which
> will most likely exist already, causing a new remote never to be
> cloned and subsequently causing hg.share to fail with error msg:
> "mercurial.error.RepoError: repository .git/hg not found"
>
> Changing shared_path to ".git/hg/.shared" will solve this problem

> and create a shared local mercurial repository for non local remotes.
> The initial dot circumvents a name clash problem should a remote be
> called "shared".
