Fisheye: fix video thumbnail regeneration and gateway timeout

- FisheyeImage::renderThumbnails: route video/* mime types through
  mime_video_create_thumbnail() instead of liberty_generate_thumbnails()
  which only handles images — fixes regeneration of existing stored videos
- edit.php: send redirect before generateGalleryThumbnails() using
  fastcgi_finish_request() so the browser is released immediately and
  bulk thumbnail generation runs in background without nginx timeout
