gerrit: some fixes for the rfc script

In rebase_changes():

- Using "--all" for git fetch is bogus: the scope of this quantification is not
  over the tracked refs of the upsteam repo (which we do want, but that kind
  of universal quantification is already implied by the notion of "tracking"),
  but over the set of all the registered remotes, which is an annoying side effect.

- $EDITOR is weaker than the git configuration settings. For the purpose of the
  script, we need to override any kind of setting, and that can be done
  via $GIT_EDITOR.

Cf. git-fetch(1), git-commit(1).
