128966: kvserver: skip rebalance multi-store under deadlock r=arulajmani a=kvoli

`TestReplicateQueueRebalanceMultiStore` spins up 8 stores and asserts on balancing of replicas and leaseholders. Under deadlock builds this is especially slow and prone to timeouts. Skip under deadlock.

Fixes: cockroachdb#128952
Release note: None
