Fixes #6462:Had a few problems using server_ubuntu

[mikes1988]

PR fixes #6462

Narrowed problem down to provision/server_ubuntu.sh.

• Install apache2 before heading towards rudder-server-root.
  • need to run a2enmod version to install mod_version, this is used in the rudder config for apache.
• fixed the deb sources.list.d lines, contrib and non-free were breaking this.

Yes, thansk @mikes1988 for the contribution.
Would it be possible to open a ticket on http://www.rudder-project.org/redmine/projects/rudder-tools/ with category "Vagrant" so that we can associate the PR with a bug ? It helps to keep track of why code was added. When done, could you also change the commit text so that it includes "Fixes #XXXX: ....", with XXXX being the ticket id.

For non-trivial contrib, we also ask if you can sign a contributor agreement as explained in http://www.rudder-project.org/foswiki/Development/HowToContribute .

Thanks again for your time and intererest !

EDIT: wow, ordering sentences is hard :)
