sound - Allow /dev/sndstat to be opened multiple times from one process.

* This still isn't great, but at least it's enough to make pulseaudio's
oss module detect the audio devices correctly.

* This now uses the buf->uio_offset, instead of trying to track the read
position ourselves in the driver with sndstat_bufptr.
