Bug#954159: pavucontrol: allow multiple instances

[Tim Connors]

Package: pavucontrol
Version: 4.0-2
Followup-For: Bug #954159

Upstream bug here: https://gitlab.freedesktop.org/pulseaudio/pavucontrol/-/issues/75

Attracting the usual level of developer interest for a freedesktop
project.

This seems to be the patch that introduced the broken behaviour:
https://gitlab.freedesktop.org/pulseaudio/pavucontrol/-/commit/f6ce4fb8db51489f6ab1210593695f465ccb83a0

Behaviour looks pretty entrenched - don't know how hard it would be to
put it all under a commandline switch.
