[Spice-devel] [client 1/3] build-sys: Allow simultaneous support for Pulse and GStreamer audio

Rather than GStreamer/PulseAudio backend being mutually exclusive at
compile-time, this commit allows to enable both at the same time.
PulseAudio will then be favoured, with a fallback to GStreamer if it's
not available.
Note that --with-audio is kept for backward compatibility.
