iv_event_raw.c patch, missing include

I have a Lemote Fuloong 2F mips64el (n32) machine running Gentoo, the uname looks like this:

Linux Lemote 3.3.0 #5 PREEMPT Wed Apr 18 13:25:19 CEST 2012 mips64 ICT Loongson-2 V0.3 FPU V0.1 lemote-fuloong-2f-box GNU/Linux

This machine doesn't get updated that often, so I didn't discover that syslog-ng didn't work before I updated syslog-ng to version 3.3.4 and then later 3.3.5
recently. Tested with glibc 2.14 and 2.15.
Running syslog-ng -d:

I checked the file lib/ivykis/modules/iv_event_raw.c as it was the only file calling the eventfd2 syscall, and I noticed that it defines EFD_NONBLOCK and
EFD_CLOEXEC if it's not already defined by the includes. I then noticed the values existed in <sys/eventfd.h>, and that the values in that file were other
values that the ones defined in iv_event_raw.c.
So I just included <sys/eventfd.h>, and that fixed the problem.

Attaching a patch fixing the problem for me.
