Don't include sys/poll.h anymore.

Browse Source 
poll.h is mandated by Single Unix Spec v2, the usual baseline for
postgres on unix.  None of the unixoid buildfarms animals has
sys/poll.h but not poll.h.  Therefore there's not much point to test
for sys/poll.h's existence and include it optionally.
