Hide refs/meta/config on git protocol v2

Fix a problem in the refs advertisement with git protocol v2
where the refs/meta/config was leaked even though the client
did not have any read access to it.

The leak was limited to the value of the SHA1 and not to the
actual content of the refs/meta/config branch. A fetch of the
SHA1 would have resulted in a WantNotValidException.

Bug: Issue 11962
