Apache overrides were not enough (#1873)

It looks like overrides of CustomLog, ErrorLog, Listen did not do the
job fully.
Updated to comment out those lines in httpd.conf.
Fixes the fact that logs were kept in /var/log/apache2/ (instead of
being only given via STDOUT to Docker logs) and the "internal dummy
connection" bug over IPv6 (Docker is typically only IPv4).
