SystemVM ISO is not installed with 4.0 on Ubuntu or Debian

[Wido den Hollander]

Hi,

I just did a fresh CloudStack 4.0 installation from the Debian packages 
we have and I found a dependency issue.

cloud-agent does not depend on cloud-system-iso, thus it doesn't get 
installed.

This took me about 2 hours to figure out why my System VMs weren't 
working properly.

I'll push a fix for this to the master branch, but this will be broken 
in the 4.0 release.

When using apt to install the Agent from the Debian repo they will have 
to manually install the system-iso package.

I'm thinking about adding this dependency to the packages on 
cloudstack.apt-get.eu to prevent this from happening to new users.
