[PATCH 1/2] gitweb: Always use git-peek-remote in git_get_references

[Jakub Narebski <jnareb@gmail.com>]

Instead of trying to read info/refs file, which might not be present
(we did fallback to git-ls-remote), always use git-peek-remote in
git_get_references.

It is preparation for git_get_refs_info to also return references
info. We cannot use info/refs for git_get_refs_info as the information
contained therein is usually stale.
