screen-cast-src: Port to pipewire master

Browse Source 
The PipeWire master branch saw some backports from the work branch,
including API changes making the 0.1 series more aligned with future
plans. Make mutter use the new API. This is needed to avoid dead locks
that existed in the older version.
