cloud/atomic: give appropriate factory-parameters to koji
In koji there are ova-options and also factory-parameters.
We can pass ova-options to koji and also factory-parameters
but we can't pass ova-options as a factory-parameter. We just
need to pass in the vagrant_sync_directory as a factory
parameter.
