tests: add a log allow list to stabilize benchmarks (#7251)

Browse Source 
## Problem

https://github.com/neondatabase/neon/pull/7227 destabilized various
tests in the performance suite, with log errors during shutdown. It's
because we switched shutdown order to stop the storage controller before
the pageservers.

## Summary of changes

- Tolerate "connection failed" errors from pageservers trying to
validation their deletion queue.
