pulseaudio: fix CVE-2014-3970

The pa_rtp_recv function in modules/rtp/rtp.c in the module-rtp-recv module
in PulseAudio 5.0 and earlier allows remote attackers to cause a denial of
service (assertion failure and abort) via an empty UDP packet.

Fix it by picking a patch from pulseaudio upstream code.
