download/git: be sure we do fetch something

Browse Source 
The different versions of git will behave in different ways when
fetching remote references, as summarised by the table below:

              |     ancient git         | new git
--------------------------------------------------------------------
git fetch     | fetch all refs but tags | fetches all refs but tags
git fetch -t  | fetches only tags       | fetch all refs and tags

(git-fetch may still fetch tags, but only if reachable from a branch)

So, to cover all the bases, we do a simple fetch, to be sure we have
branches, followed by the existing fetch -t, to get extra tags.
