Fix hanging local cluster test: test_validator_exit_2

[CriesofCarrots]

Problem

Local cluster tests hang in CI, on test test_validator_exit_2 since #9560 . Test never sees active stake in gossip -- get_stake_percent_in_gossip no longer includes the current node, and local cluster never reaches this line https://github.com/solana-labs/solana/blob/master/local-cluster/src/local_cluster.rs#L272 -- so loops indefinitely.

Summary of Changes

Remove wait_for_majority config setting

@mvines , another solution would be to restore the else if case to get_stake_percent_in_gossip() here

solana/core/src/validator.rs

Line 838 in f142451

} else {

like:

} else if vote_state.node_pubkey == cluster_info.read().unwrap().id() {
            online_stake += activated_stake;
}

But I assume that was a deliberate choice for the the 80% to not include the current node.
