repo: add the flag -z as an alias for --format=nul

Browse Source 
Other Git commands that have nul-terminated output (e.g. git-config,
git-status, git-ls-files) have a flag `-z` for using the null character
as the record separator.

Add the `-z` flag to git-repo-info as an alias for `--format=nul`,
making it consistent with the behavior of the other commands.
