The warning if something stops SIGPIPE being ignored has always been deferred as the signal calls are made before main() has run. However, the place the warning was deferred to could result in it being logged many times because the deferred logging was in a method that could be called many times. This change moves that deferred logging to a dedicated method that can just be called once. Backport of elastic#1221
