Patch to fix build with clang

With the latest release (0.3.1) xfce4-pulseaudio-plugin fails to build with clang (it's default compiler on FreeBSD for Tiers-1 architectures arm, i386 and amd64). Patch fixes this issue, otherwise I get this error:

pulseaudio-volume.c:813:3: error: non-void function 'pulseaudio_volume_get_outpu
