prop224: Add the dir purpose HAS_FETCHED

Once a descriptor has been successfully downloaded from an HSDir, we flag the
directory connection to "has fetched descriptor" so the connection subsystem
doesn't trigger a new fetch on success.

Same has DIR_PURPOSE_HAS_FETCHED_RENDDESC_V2 but for prop224.
