Log when listening (#350)

* Log when starting letsencrypt endpoint + clearer errors

Running `gotosocial server` with the default configuration will try to
bind to :80 and listen for letsencrypt challenges, which will fail if
running as non-root (w/o capabilities), or if eg. nginx hogs the port.

When that happens, this should make it more obvious what's wrong.

* Log what address/port we're listening on

Always nice not to have to guess. Also feels more consistent than just
doing it for the letsencrypt endpoint.
