git-cherry: make <upstream> parameter optional

The upstream branch <upstream> now defaults to the first tracked
remote branch, which is set by the configuration variables
branch.<name>.remote and branch.<name>.merge of the current branch.

Without such a remote branch, the command "git cherry [-v]" fails with
usage output as before and an additional message.
