Subject: stdlib: use IO#wait_*able instead of IO.select when possible

In case a process encounters high-numbered FDs, this allows
consistent performance on systems with ppoll support.
[ruby-core:35572]

* ext/socket/lib/socket.rb (connect_nonblock): use IO#wait_writable
* lib/drb/drb.rb (DRB::DRbTCPSocket#alive?): use IO#wait_readable
* lib/webrick/httpserver.rb (run): ditto
* lib/resolv.rb (request): ditto for single socket case
  [ruby-core:68943] [Feature #11081]
