Subject: [PATCH] Set specific media.role for pulsesink probe.

Some PulseAudio modules, like module-role-ducking and module-role-cork
rely on media.role for their operation. Pulsesink probe stream has the
same media.role property as the resulting playback stream, which causes
unneccessary and distruptive actions in aforementioned modules.
Set/overwrite pulsesink probe stream's media.role property so that probe
stream can be distinguished from resulting stream more easily.
