Description:

Export GStreamer version in pkgconfig variable

Some plugins like pidgin-sipe want to know which version of GStreamer
we're built against. It currently assumes that libpurple-3 will be using
gstreamer-1.0 and libpurple-2 will be using gstreamer-0.10.

That isn't strictly true since libpurple-3 *can* be built against
gstreamer-0.10. And it gets even less true when we allow libpurple-2 to
be built against gstreamer-1.0 (qv).

This exports the information so that it's available by running
	pkg-config --variable=gstreamer purple-3
and we don't have to guess.
