openal-soft: update to 1.22.1.

openal-soft-1.22.1:

    Fixed CoreAudio capture.

    Fixed air absorption strength.

    Fixed handling 5.1 devices on Windows that use Rear channels instead of
    Side channels.

    Fixed some compilation issues on MinGW.

    Fixed ALSA not being used on some systems without PipeWire and PulseAudio.

    Fixed OpenSL capturing noise.

    Fixed Oboe capture failing with some buffer sizes.

    Added checks for the runtime PipeWire version. The same or newer version
    than is used for building will be needed at runtime for the backend to
    work.
