Fix 404 errors for blowfish/fishfinger index.txt URLs

Added blowfish.buetow.org and fishfinger.buetow.org to @acme_hosts array
to ensure proper routing through relayd to localhost instead of falling
through to f3s cluster backends.

Changes:
- Rexfile: Add blowfish.buetow.org and fishfinger.buetow.org to @acme_hosts
- httpd.conf.tpl: Skip current server hostname in @acme_hosts loop to avoid
  duplicate server blocks (already handled by dedicated "Current server's FQDN" block)
- relayd.conf.tpl: Skip both server hostnames in TLS keypair loop since each
  server only has its own certificate (not the other server's cert)

This ensures relayd routes these hostnames to localhost:8080 where httpd
serves content from /htdocs/buetow.org/self including index.txt health checks.
