Martin von Zweigbergk edf7ec0a72 git: don't fetch tags we're not fetching commits for
In the recent switch away from `git2::Remote::fetch()`, I passed
`git2::AutotagOption::All`, which caused cloning of e.g. the `clap`
repo to fail like this:

```
Error: Fetch failed: Error { code: -1, klass: 4, message: "target OID for the reference doesn't exist on the repository" }
```

This commit changes from `All` to `Unspecified`, which respects the
remote's configuration.
