With d373b7b452 feed icon modification times get used for cache-busting, but 'Cache_Local' updates that
value on each send. This change makes it so the modification time only gets updated on files in expirable caches, keeping the value
consistent between sends for files in non-expiring caches.
Also, marking 'Cache_Local::send_local_file()' private since it's unique to that adapter.
