arb_framebuffer_object: Add tests to check GL_DEPTH_STENCIL_ATTACHMENT

Add the following tests:
	specs/ARB_framebuffer_object/same-attachment-glFramebufferRenderbuffer-GL_DEPTH_STENCIL_ATTACHMENT
	specs/ARB_framebuffer_object/same-attachment-glFramebufferTexture2D-GL_DEPTH_STENCIL_ATTACHMENT

The tests check that if an object is attached to the
GL_DEPTH_STENCIL_ATTACHMENT point, then it is also attached to the
GL_STENCIL_ATTACHMENT and GL_DEPTH_ATTACHMENT points.

v2:
  - Make tests run concurrently.
  - Move test body from piglit_display() to piglit_init().
