MEDIUM: init: continue to enforce SYSTEM_MAXCONN with auto settings if set

Commit d025648 ("MAJOR: init: automatically set maxconn and/or maxsslconn
when possible") resulted in a case where if enough memory is available,
a maxconn value larger than SYSTEM_MAXCONN could be computed, resulting
in possibly overflowing other systems resources (eg: kernel socket buffers,
conntrack entries, etc). Let's bound any automatic maxconn to SYSTEM_MAXCONN
if it is defined. Note that the value is set to DEFAULT_MAXCONN since
SYSTEM_MAXCONN forces DEFAULT_MAXCONN, thus it is not an error.
