[PATCH 5/5] cgit: type declaration for PublicInbox::Git

[Eric Wong <e@80x24.org>]

AFAIK this doesn't do anything for Perl internally since
PublicInbox::Git doesn't "use fields", but it makes it easier for
humans readers to follow and ensure we're not passing unblessed
or non-ref scalars to PublicInbox::GitHTTPBackend::serve.
