check_smtp: certificate check is no longer opt-in

This is a breaking change.
Testing whether a TLS certificate is still valid (expiration wise)
is now the default in check_smtp.
The reasoning is, that in most scenarios an expired certificate
will effectively mean that the service is not working anymore due to
the refusal of other software to talk to it.

There is a new cli parameter though to explicitly ignore that.
