[c-nsp] Matching all MPLS traffic for a class map

Unfortunately because there's no IP involved, I don't think it would
work.  I could attempt to match it on ingress interface, but I have a
feeling that there's no "ingress interface" known to it on the egress
interface because the traffic was technically sourced at the router (as
mpls) when it was transformed from ATM.
