Treat a WAL sender process that hasn't started streaming yet as a regular backend, as far as the postmaster shutdown logic is concerned. That means, fast shutdown will wait for WAL sender processes to exit before signaling bgwriter to finish. This avoids race conditions between a base backup stopping or starting, and bgwriter writing the shutdown checkpoint WAL record. We don't want e.g the end-of-backup WAL record to be written after the shutdown checkpoint.
