lib/net/*: use io/wait methods instead of IO.select

io/wait is expected to work on any platform where sockets are
supported.  io/wait methods uses fewer allocations and uses
ppoll internally under Linux for better performance on
high-numbered FDs.

[ruby-core:35572] describes the performance advantage of ppoll
on high-numbered FDs.

* lib/net/protocol.rb (rbuf_fill): use IO#wait_*able
* lib/net/http/generic_request.rb (wait_for_continue): ditto


I'll commit in a few days unless there are objections.
