credential: let empty credential specs reset helper list
Sine the credential.helper key is a multi-valued config list, there's no way to "unset" a helper once it's been set. So if your system /etc/gitconfig sets one, you can never avoid running it, but only add your own helpers on top. Since an empty value for credential.helper is nonsensical (it would just try to run "git-credential-"), we can assume nobody is using it. Let's define it to reset the helper list, letting you override lower-priority instances which have come before.
