Subject: [PATCH] audio: Build on OpenBSD

OpenBSD supports PulseAudio and OpenAL, but not ALSA.
Either PulseAudio or ALSA are required for libtgvoip.

Add missing OS macros to enable building with
`LIBTGVOIP_DISABLE_PULSEAUDIO=ON` `LIBTGVOIP_DISABLE_ALSA=OFF` as tested
on OpenBSD/amd64 7.2-current.
