    ve/net/ip6tables: fix autoloading of the ip6table_raw module from CT
    
    Currently autoloading of the ip6table_raw module is forbidden
    from container, leading to:
         ip6tables-restore v1.4.21: ip6tables-restore: unable to initialize table 'raw'
    
    If use of ip6tables is allowed in container, autoloading of the ip6tables_raw
    has to be permitted as well.
