K_StartCeremony: Directly modify spectator status for bots as early as possible

The problem with bots randomly going towards the same spot in podium was...
- If you failed a Sealed Star, K_UpdateGrandPrixBots wouldn't make the puppies non-spectators
- P_SpawnPlayer catches the spectator status...
- ...but it's in a loop that calls K_GetPodiumPosition...
- ...which ignores spectators...
- ...which means this is too late to catch it, so we simply have to do it earlier.
Also short circuits P_SpawnPlayer's and K_UpdateGrandPrixBot's attempts to set so the author of this commit can be certain what is being done is correct
