 `clean_blog_cache()` currently invalidates keys
 `current_blog_{$blog->domain}` and
 `current_blog_{$blog->domain}_{$blog->path}` of the `site-options` group.
 As far as I can see those keys are not used anywhere in Core (and have not
 been used for quite a while), so we should be able to remove them from
 that function.
