build-sys: Alias bash-completion for all PulseAudio commands

Bash-completion 1.90 introduced support for on-demand loading
of completions. Install the completion file as 'pulseaudio' to match
the main command, and create symlinks as aliases for other supported
commands in order to support the new system.
