Subject: [PATCH] Add a dummy route for /.well-known/host-meta

This was removed from the diaspora_federation gem, since it's not used
for the federation/discovery anymore since a long time. But old versions
of the ConnectionTester up to version 0.7.17 still check if this route
exist or else they mark the pod as offline. So lets add a dummy
host-meta with an empty response back, so the ConnectionTester is happy
again until we can remove this workaround again.
