Title: Fix cmake support for portaudio

The first commit fixes two issues with finding portaudio via pkg-config. The second of these commits verifies that the located version is not portaudio18, which would produce an error when gr-audio is built. (Ubuntu 12.04-LTS and possibly other distributions do still use portaudio18 by default and installing libportaudio19-dev is not always an option.)
