Remove select(2) backed latch implementation.
poll(2) is required by Single Unix Spec v2, the usual baseline for
postgres (leaving windows aside). There's not been any buildfarm
animals without poll(2) for a long while, leaving the select(2)
implementation to be largely untested.
On windows, including mingw, poll() is not available, but we have a
special case implementation for windows anyway.
