Include audiotest.au again
These files were removed because historically they included
a short sound clip from Monty Python shows, which might fall
In 2010 this was replaced upstream by a recording of Guido
van Rossum saying something silly in Dutch. So, there's no
reason to exclude the file anymore.
The bug mentioned in the removed comment is private due to
corporate policy from 2004. Sorry for that!
The problem itself is discussed at: http://bugs.python.org/issue7755
