Sometimes it's necessary to fetch a git repository at a revision and it's unknown which ref contains the revision in question. An example would be a Cargo.lock which only provides the URL and the revision when using a git repository as build input. However it's considered a bad practice to perform a full checkout of a repository since this may take a lot of time and can eat up a lot of disk space. This patch makes a full checkout explicit by adding an `allRefs` argument to `builtins.fetchGit` which fetches all refs if explicitly set to true. Closes #2409
