unstableGitUpdater: Fix support for fetchFromGit{Hub,Lab}

When `fetchFromGitHub` uses `fetchzip` instead of `fetchgit` internally,
which is the most common use case, there is no `src.url` attribute
so the update will fail.

Let’s fix that by falling back to `src.meta.homepage`,
which these fetchers set to the repository URL.
