tests/core_hotunplug: properly finish processes using audio devices
Before unloading or unbinding an audio driver, all processes
that are using it must be terminated. The current logic seeks
only for alsactl, but ignore other processes, including
pulseaudio.
Make the logic more general, extending it to any processes that
could have an open device under /dev/snd.
It should be noticed that some distros like Fedora and openSUSE
are now migrating from pulseaudio into pipewire-pulse. Right
now, there's no standard distribution-agnostic way to request
pipewire-pulse to stop using audio devices, but there's a new
patch upstream that will make things easier:
https://gitlab.freedesktop.org/pipewire/pipewire/-/commit/6ad6300ec657c88322a8cd6f3548261d3dc05359
Which should be available for pipewire-pulse versions 0.3.50 and
upper.
