[Devel] [PATCH rh7] net/ip6tables: fix autoloading of the ip6table_raw module from CT

[Andrey Ryabinin]

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.
