Install script should check if zamba.conf exist

[fbartels]

Currently when someone just clones the repo and runs install the start of a new container will fail:

# ./install.sh
1) checkmk	     3) debian-unpriv	 5) matrix	     7) onlyoffice	 9) proxmox-pbs	    11) zmb-ad		13) zmb-standalone
2) debian-priv	     4) mailpiler	 6) nextcloud	     8) open3a		10) urbackup	    12) zmb-member	14) quit
#? 2
