Check for GStreamer plugins individually

In configure.ac, check for individual GStreamer plugins, instead of
requiring gstreamer-plugins-bad-0.10.pc. This is because Ubuntu doesn't
have a devel package for gstreamer-plugins-bad, and we don't actually
link against that library - we just dynamically open it.
