email_server: Adjust TLS configuration parameters
- Don't add TLS debugging information to Received: header.

- Drop unused fingerprint digest configuration. They are only used when
smtpd_tls_security_level is set to 'fingerprint' in which case certifying
authorities are ignored.

- Drop alterations to TLS low/high cipher lists. They are not used since
tls_ciphers are all set to 'medium'.

Tests:

- No configuration errors are reported by postfix in its logs after startup.

- 'postconf' shows that the new configuration parameters are set properly.
