Older versions of libpipewire-0.3 don't have pw_check_library_version

Trying to compile niri 26.04 on debian stable (bookworm at the time of writing). Compilation fails because it's missing a symbol from libpipewire. Please see similar issue and the fix in SDL (it's explained in the commit comment): https://github.com/libsdl-org/SDL/commit/1d0ecf982f0a6d30fa20c4a8115097e2333b3c54:

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