Brian Geffon 3e2d4df574 perf tools: sched-pipe bench: add (-n) nonblocking benchmark 
The -n mode will benchmark pipes in a non-blocking mode using
epoll_wait.

This specific mode was added to demonstrate the broken sync nature
of epoll: https://lore.kernel.org/lkml/20240426-zupfen-jahrzehnt-5be786bcdf04@brauner
