Shokunin a069f1ca0c Netplay rb: followers apply the dual-initiation tie-break ...

With three or more seats two guests can mispredict the same tick and both
BEGIN. The tie-break (lower initiator slot wins) ran only on initiators,
so a follower followed whichever BEGIN arrived first and stashed the rest.
On a 4-seat WAN race the host followed slot 3's epoch while slot 1's won;
the seats split across epochs, each waited for baselines that never came,
and the match ended after 20 s at rb_baseline.

The epoch id names its initiator, so a follower now applies the same rule
to the episode it follows (netplay_rb_concurrent_begin): yield during the
handshake and follow the winner, or drop the loser's BEGIN. A follower
seeing a new epoch from the initiator it already follows (abort and
reopen, the only case two seats can produce) is unchanged.
