Chris Lu 8cf42a5abb test(s3/lifecycle): assert per-goroutine errors in fake-server concurrent test (#9393)
test(s3/lifecycle): assert per-goroutine errors in concurrent fake test

The previous TestFake_ConcurrentCallsSerializeWithoutDeadlock dropped
the err return from each LifecycleDelete call, so a regression in the
concurrent path could pass the length-only assertion. Capture each
err on a buffered channel and require.NoError after wg.Wait().
