mainloop: Set client role if ControlPort is set

Browse Source 
It turns out that if _only_ the ControlPort is set and nothing else, tor would
simply not bootstrap and thus not start properly. Commit 67a41b6306
removed that requirement for tor to be considered a "client".

Unfortunately, this made the mainloop enable basically nothing if only the
ControlPort is set in the torrc.

This commit now makes it that we also consider the ControlPort when deciding
if we are a Client or not. It does not revert 67a41b6306 meaning
options_any_client_port_set() stays the same, not looking at the control port.

Fixes #27849.

o Major bugfixes (mainloop, bootstrap):
- Make sure Tor bootstraps and works properly if only the ControlPort is
set. Prior to this fix, Tor would only bootstrap with at least a client
port being set (Socks, Trans, NATD, DNS or HTTPTunnel port). Fixes bug
27849; bugfix on 0.3.4.1-alpha.
