[PATCH v4 3/3] Run PipeWire and WirePlumber in the VMs

[Demi Marie Obenour <demiobenour@gmail.com>]

WirePlumber is completely overkill as a session manager here, and
ideally a trivial session manager would be used instead.  I did build a
Spectrum OS image and found that PipeWire and WirePlumber both
successfully started.  PipeWire is configured to listen on the
PulseAudio socket, so PulseAudio compatibility works.  This does inject
a large number of completely unnecessary files into the VM, notably for
libcamera and Bluetooth support.

Notes:
    I tested this with QEMU virtio-sound, but I am not sure if the paramters
    are correct.  In particular, the sample rate might well be wrong.
