mesa: fix frag shader generation for alpha test with no color buffers

If alpha test is enabled and there's no color buffers we still need the
fragment shader to emit a color.

v2: add _NEW_COLOR flag in _mesa_update_state_locked()

Fixes piglit fbo-alphatest-nocolor-ff failures with Gallium drivers.
