pipewire: Don't require pw_check_library_version() with Pipewire < 0.3.75

Browse Source 
The Debian 12 'bookworm' stable release only has 0.3.65, which is earlier
than the introduction of that symbol. Similarly, Steam Runtime 3 'sniper'
and Steam Runtime 2 'soldier' have a backport of 0.3.65 from Debian 12,
so they have the same limitation.
