i965/fs: Set LastRT on the final FB write on Broadwell.
In Piglit's EXT_framebuffer_multisample/alpha-to-coverage-dual-src-blend test, key->nr_color_regions == 2, but the dual source blend FB write has ir->target set to 0. So we failed to set "Last Render Target Select" on any FB write message. We only emit one FB write per render target, so my comment about setting LastRT on every FB write directed at the last color region is a bit... misinformed. According to the documentation, depth buffer writes and scoreboard updates happen on the FB write with LastRT set, so I believe we want to set it only once.
