[Piglit] [PATCH 3/4] clear-accum: specify config.requires_displayed_window = true

[Brian Paul]

The accumulation buffer can only be present with the window system
framebuffer, not an FBO.  So this test fails if run with -fbo.
Set the config.requires_displayed_window option to true to require
a window system buffer.
