pulseaudio: Revert "pulseaudio: Require PulseAudio 5.0 or later for SDL3." 

This reverts commit 6fd0613ac8.

Turns out that the Steam Runtime is still on PulseAudio 1.1, and the only
thing we (currently) need a newer Pulse for is pa_threaded_mainloop_set_name,
so let's just go back to treating that symbol as optional.

We might need to force a higher version at some point, but it's not worth it
over this.
