gl-3.0: Test clearing depth buffers with glClearBufferfv
This test passes on Mesa's swrast, Mesa's i965, and AMD's
closed-source driver. It fails on NVIDIA's closed-source driver
because they incorrectly generate a GL_INVALID_ENUM error on the
glClearBufferfv(GL_DEPTH) call when there is no depth buffer.
