qt4: make pulseaudio support conditional upon DISTRO_FEATURES

Add a pulseaudio DISTRO_FEATURES item and disable pulseaudio support in
phonon within Qt4 if it is not present; otherwise it is a race condition
as to whether it is enabled or disabled or breaks the build.

Note that this adds pulseaudio to DISTRO_FEATURES_BACKFILL thus leaving
existing distro configurations unaffected.
