pulseaudio: Move Pulseaudio include in correct place when using autoc…

…onf (#843)

As Jack and Pulseaudio both needs Ringbuffer that include can
be done in same place. In configure.in also Pulseaudio header
file was included before it was sure that it was really needed.

Commit makes sure that Pulseaudio include is available only if
it's needed as it can cause failing in build if Pulseaudio
develoment files are not available.
