debian stretch slim (#784)

* Switch to stretch-slim as base image.
 - first step correct the testdata, as newer packages are more strict
about the mail-structure.

* Switch to stretch-slim: correcting the test-environment and the build
 - add missing build-step to make
 - clean the userdb aswell
 - use timeout of netcat, as postgrey would not close the connection
 - there is 2 extra mail-logs -> assert_output 5
 - cosmetic: use "" instead of ''

* Switch to stretch-slim:
new image:
 - smaller size
 - 0 CVEs compared to 11 CVEs in ubuntu 16.04 Image
better backport situation
 - postfix 3.1.6 vs 3.1.0
 - fail2ban 0.9.6 vs 0.9.3
 ...
changes needed because of stretch-slim:
- add missing gnupg and iproute2 package
- remove non-free rar, unrar-free should do
- rsyslog does not add syslog user and has different conf-structure
- pyzor command discover was deprecated and is missing in the new
stretch package

- dovecot does not know SSLv2 anymore. removed because of warnings in
log

- iptables does not know imap3, IMAP working group chose imap2 in favor
of imap3

* Switch to debian stretch slim:
SSLv2 seems to be a not known protocol anymore - good!

* switch to debian stretch slim:
make this test more stable. there might be more than only one mail.log
(mail.info, mail.warn, ...)

* switch to debian stretc slim:
 new openssl 1.1.0 needs stronger ciphers, removed some weekers ones.
Please, look through the new list of cipher! this needs to be done in
another commit for all other SSL/TLS-Endpoints aswell.

* Switch to debian stretch slim:
let our server pre-empt the cipher list.
Did a read through, wwwDOTpostfixDOTorg/FORWARD_SECRECY_READMEDOThtml
and
wwwDOTpostfixDOTorg/TLS_READMEDOThtml

* Switch to debian stretch slim: lets give this openssl-based test a new and independent but identical container.  many other test on the main 'mail' container might interfere here.

* Switch to debian stretch slim: remove unused lines
