Checkbox "Create new" in "Groups" row in import form should not be accessible for non-super admins

1. Log in as regular admin;
2. navigate to host or template import;
3. observe "Groups" row and "Create new" column - checkbox is selected and enabled;
4. try import something and get an error from API saying that there are no permissions to call hostgroup.create.

This checkbox should either be disabled or better not be visible at all to non-super admins.
