ndnfdc: set InterestLifetime in commands

ccndc calls ccn_get with 1000ms timeout, but InterestLifetime is left at 4000ms default, which causes timing issue in new forwarding strategy.
ndnfdc solves this by setting InterestLifetime to 750ms.
TcpFaceFactory::DoConnect should set FaceKind
FaceMgmt_test: drop NDNFD+ccndc tests

ccndc leaves InterestLifetime at 4000ms but ccn_get limits to 1000ms.
