pulseaudio: improve PACKAGECONFIG for dbus/consolekit dependencies
* the problem is that consolekit module is built whenever dbus is enabled
and consolekit is available only in distributions with x11 in DISTRO_FEATURES
* many distributions want to enable dbus support (required for bluez support),
but without consolekit because they aren't using x11
* allow to completely disable dbus (and consolekit)
* add consolekit runtime dependency only for x11 in DISTRO_FEATURES
