d/control: Disable lirc module and dependency

• pulseaudio depends on lirc to build with pulseaudio-module-lirc module.
• lirc depends on libftdi1, which depends on libconfuse.
• libconfuse should be imported from debian.

This MR disables lirc support in pulseaudio as we don't need that. This will avoid pulling more packages into development and possibly drop a few packages in the dep chain.
