This patch will change the name of the config file from `traefik` to
`traefik.conf`, since tor now includes `/etc/torrc.d/*.conf` in their
config file. This should make sure that the config is actually loaded.
This patch originates from the observation that new setups no longer
create the tor hidden service for traefik. Some investigation resulted
in the insight, that the tor node is no longer including the
configuration file.
