Ignore server-side delays when enforcing wal_sender_timeout.
Healthy clients of servers having poor I/O performance, such as
buildfarm members hamster and tern, saw unexpected timeouts. That
disagreed with documentation. This fix adds one gettimeofday() call
whenever ProcessRepliesIfAny() finds no client reply messages.
Back-patch to 9.4; the bug's symptom is rare and mild, and the code all
moved between 9.3 and 9.4.
