remove 'when is defined' in main.yml (#28)

Remove 'when is defined' for dostros/profils/systems

Remove conditions 'when is defined' for cobbler_distros,
cobbler_profiles and cobbler_systems, to avoid silent failure.

Set those vars empty as default.
(to avoid a breaking change caused by deleting "when is defined")
