Feature #9427: [PATCH] io.c: remove socket check for sendfile
https://bugs.ruby-lang.org/issues/9427

* Author: Eric Wong
* Status: Open
* Priority: Normal
* Assignee: Akira Tanaka
* Category: core
* Target version: current: 2.2.0
----------------------------------------
Linux uses splice internally for sendfile since 2.6.23, allowing
sendfile to work for arbitrary destinations.

We gracefully handle EINVAL/ENOSYS from sendfile anyways,
so we will hit the old fallback to read/write if the system
cannot perform sendfile to non-sockets.


Verified using strace on the following one line script:
  IO.copy_stream(__FILE__, "/dev/null")
