sysutils/nut*: Enable all non-experimental options by default

Increasingly binary package users are requesting enablement of all options
to avoid building ports themselves, while others lack the wherewithal to
build ports themselves. Therefore enable all non-experimental options by
default. And, while at it enable openssl support.

Users who either build ports themselves or maintain their own
poudriere infrastructure, the ease of running make config or
poudriere options is certainly the lesser of the two evils.
