For mulitcons boot, report it and which console is primary

Browse Source 
Until we can do proper /etc/rc output on both consoles in multicons
boot (or all of them if we ever generalize), report when we are
booting multicons. Also report the primary console. This will be a big
hint why output stops after this line (though some slow USB discovery
still happens after mountroot / init starts).
