git_repository: return actual commit

Using that repository rules now may return a non-None value,
make git_repository return the arguments that make the rule
reproducible; in particular, return the actual commit (instead
of a tag) and the date of the commit, so support shallow clones.

The added test also demonstrates how the `bazel sync` command
together with `--experimental_repository_resolved_file` can be
used to replay an earlier state of external dependencies.
