In the circuit_about_to_free(), we clear the circ->conflux object and then we
end up trying to emit an event on the control port which calls
CIRCUIT_IS_CONFLUX() and non fatal assert on the false branch.

resolve scary vanguard-related log msgs on dir auths

See merge request !873

After we added layer-two vanguards, directory authorities wouldn't
think any of their vanguards were suitable for circuits, leading
to a "Failed to find node for hop #2 of our path. Discarding
this circuit." log message once per second from startup until
they made a fresh consensus. Now they look to their existing
consensus on startup, letting them build circuits properly from
the beginning.

Fixes bug 40802; bugfix on 0.4.7.1-alpha.

These would fail if anybody actually still used OpenSSL 1.0, but in any case

Part of #40836.

Note that the changes here will require all relays
to be 0.4.7.4-alpha or later, which is lower than
our current lowest-supported relay version.

Part of #40836.

Only include custom OpenSSL ABI checks for OpenSSL 1.1

Unfortunately, we wanted to be able to control the Guard flag here but the
token used mentionned "exit" instead.

Oh well, s*** happens :).
