nicoseiga: fix login endpoint.

* Update the login endpoint. The old endpoint returns 404 now.

  POST https://account.nicovideo.jp/api/v1/login ->
  POST https://account.nicovideo.jp/login/redirector?site=seiga

* Let Danbooru::Http cache the login request instead of caching it manually.

* Let Danbooru::Http automatically follow redirects instead of dealing
  with the Location header manually.
