lprint.c: Enable TLS support in Web UI

Currently (1.3.1) there is no way how to turn TLS web UI pages, because
system callback does not set WEB_TLS option by default, and checks only
for `no-tls` when processing server options.

This can be fixed by two way, depending on which default settings we
prefer. The PR enables TLS pages by default, leaving to user whether he
wants them to be disabled.

Do let me know if you would prefer the other way around.
