This commit is part of the series that introduces the new subcommand git-repo-info. The flag --is-bare-repository from git-rev-parse is used for retrieving whether the current repository is bare. This way, it is used for querying repository metadata, fitting in the purpose of git-repo-info. Then, add a new field layout.bare to the git-repo-info subcommand containing that information.
