solaris: Illumos does not ship with SOUND_PCM* functionality

Code reference:
https://github.com/joyent/illumos-joyent/blob/master/usr/src/uts/common/sys/audio/audio_oss.h

Add autoconf checks for:
- SOUND_PCM_READ_RATE
- SOUND_PCM_READ_CHANNELS
- SOUND_PCM_READ_BITS

Some platforms like SunOS (Illumos) may ship without SOUND_PCM_* functionality

Thanks to Jonathan Perkin (Joyent) for Illumos code reference.
