ao_pulse: remove hacks for ancient PulseAudio versions

This was needed by very old (0.9) versions only. Get rid of it.

Unfortunately, I can't cross-check with the original bug report, since
the bug URL leads to this:

Internal Server Error

TracError: IOError: [Errno 2] No such file or directory: '/home/lennart/svn/trac/pulseaudio/VERSION'
