Use a shorter name for the top-level vimage container holding all

virtual nodes in an experiment, so that a string in form of
ifname@eid.nodeid could fit into 15 characters or less for all node
ids smaller than n1000.  The 15 chatacter string length limitation
is derived from the IF_NAMESIZE constant which applies when specifying
interface names.  Longer eids were previously causing trouble when
attempting to open a bpf tap in child nodes.
