softpipe: set dirty_render_cache in softpipe_clear()
This fixes a bug seen when doing a glDrawPixels(GL_STENCIL_INDEX) right
after a glClear(). The check-for-flush test was failing because we
didn't set the dirty_render_cache flag in softpipe_clear(). So we saw
stale data when we mapped the stencil buffer.
