gallium: remove PIPE_SHADER_CAP_OUTPUT_READ
r600g is the only driver which has made use of it. The reason the CAP was added was to fix some piglit tests when the GLSL pass lower_output_reads didn't exist. However, not removing output reads breaks the fallback for glClampColorARB, which assumes outputs are not readable. The fix would be non-trivial and my personal preference is to remove the CAP, considering that reading outputs is uncommon and that we can now use lower_output_reads to fix the issue that the CAP was supposed to workaround in the first place.
