Fix confusion when scanning TLS-1.3-only hosts

When scanning hosts which offer only TLS 1.3 under some circumstances (e.g. using
MacOS) the scan stopped and prompted the user . It happened always when $OPENSSL
supported TLS 1.3. It did not when this was not the case.

This fixes that (see #3083) for 3.3dev by just skipping the rest in determine_optimal_proto()
when TLS13_ONLY is true.

Also it fixes missing line feeds for servoce detecttion and order in which DNS HTTPS
RR are displayed.
