drops older gossip packets when load shedding (#13364)

Browse Source 
Gossip drops incoming packets when overloaded:
https://github.com/solana-labs/solana/blob/f6a73098a/core/src/cluster_info.rs#L2462-L2475
However newer packets are dropped in favor of the older ones.
This is probably not ideal as newer packets are more likely to contain
more recent data, so dropping them will keep the validator state
lagging.
