Fix up the build for the STARTTLS version of sendmail (again). This method
mimics that of tcpdump in that for normal builds, sendmail will only be
built once. For 'make release', it is built once for the bin dist and
once for the crypto dist. This method also removes the need for two separate
Makefiles (which could become out of sync).

Assisted by: kris

Activate the 'secure' (TLS) version of sendmail if !NO_SENDMAIL && !NO_OPENSSL

Don't build sshd if NO_OPENSSL defined.
