Subject: [PATCH] Dockerfile : avoid munin cron tasks and associated logs

Avoid this logs :
(CRON) info (No MTA installed, discarding output)
(munin) CMD (if [ -x /usr/bin/munin-cron ]; then /usr/bin/munin-cron; fi)
(root) CMD (if [ -x /etc/munin/plugins/apt_all ]; then /etc/munin/plugins/apt_all update 7200 12 >/dev/null; elif...
(root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)

Unsuccessful test : Deletion fo munin have this consequence :
AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf:
Invalid Mutex directory in argument file:/var/lock/apache2
