Remove demos that have moved to git+ssh://git.freedesktop.org/git/mesa/demos.

The remaining programs are ones I've had difficulty finding a build
environment for to make the build system or are unit tests that should
probably live next to their code instead.  Hopefully people can bring
over the build for remaining pieces they care about.
