package/pulseaudio: explicitly enable/disable WebRTC support

Currently, pulseaudio optionally depends on webrtc if it is enabled.

However, it is never explcitly enabled or disabled, although
pulseaudio's ./configure has --enable/disable-webrtc-aec.

Forcibly enable/disable webrtc support using those options.
