audio/pipewire-spa-oss-ng: Update to 0.9.11

Harden live FreeBSD OSS behavior: reconnect devd monitors, improve
busy-owner diagnostics, probe exclusive rates without consuming PCM
channels, keep capture nonblocking, correct mixer state, release streams
on Suspend, and guard setup-phase streams from a live queue-sampling
assertion that could abort the data thread.

Expand OSS format support, cache companded silence fills, stabilize
adaptive scheduling, and adopt libc's typed FreeBSD ioctl helpers.
