Adjust comment about timeout when waiting for WAL at recovery
A timeout of 5s is used when waiting for WAL to become available at
recovery so as the startup process is able to react promptly if a
trigger file shows up. However this missed the fact that the startup
process also relies on the timeout to check periodically the status of
any active WAL receiver.
