Ni! File `usr/lib/spa-0.2/libcamera/libspa-libcamera.so` isn't found when installing pipewire.

This seems to affect screen sharing on wayland through wireplumber, or at least my setup broke once the messages below started appearing:

```

M 22:57:06.048626          wp-device ../source/lib/wp/device.c:619:wp_spa_device_new_from_spa_factory: SPA handle 'api.libcamera.enum.manager' could not be loaded; is it installed?
M 22:57:06.048653   script/libcamera libcamera.lua:173:chunk: PipeWire's libcamera SPA missing or broken. libcamera not supported.

```

Cheers, ale
