Updated p5-IO-Socket-SSL to 2.039.

2.039 2016/11/20
- OpenSSL 1.1.0c changed the behavior of SSL_read so that it now returns -1 on
  EOF without proper SSL shutdown. Since it looks like that this behavior will
  be kept at least for 1.1.1+ adapt to the changed API by treating errno=NOERR
  on SSL_ERROR_SYSCALL as EOF.
