Port patch

The OSS4 backend doesn't work on FreeBSD, it uses many IOCTL that are not
supported, I don't think it can be patched to make it working, using OSS3 seems
the right thing.

kmix tries to use other backends first (ALSA for sure, PulseAudio optionally),
but fallback to OSS if it cannot find a working mixer, that is what's
happening.

Jonathan Marten <jonathan.marten at kdemail.net> should be alerted about it:
https://invent.kde.org/multimedia/kmix/-/blob/da4dff77f9db4fac5c8157472c4512675
1825a04/README.oss4

Anyway, my patch simply revert to the previous situation, disabling OSS4
unconditionally and enabling OSS3.
