Fix issue that pulseaudio freezes when pausing audio

Fix issue that pulseaudio freezes when pausing audio

This patch is ported from Debian/Ubuntu.

When using glibc-2.21 or later on linux kernel < 3.14.3,
this issue should be produced.

Original patch is here:
https://sources.debian.net/patches/glibc/2.22-5/arm/local-arm-futex.diff/

AGL needs this patch because the version of kernel for
porter board is 3.10 (later kernel is not supported).

This patch and recipe is a provisional until upstream
(poky) would be fixed.

Thanks Isogai-san to find and test this patch.
