No IPv6 autoconfiguration

[steglicd]

currently net.ipv6.conf.all.accept_ra is set to true but net.ipv6.conf.all.forwarding is also set to true. This means that net.ipv6.conf.all.accept_ra is ignored and no RA's are accepted.

To fix this net.ipv6.conf.all.accept_ra needs to be set to a value of 2.

(If freedombox should accept RA's). As freedombox uses IPv4 DHCP on default, I would assume that the box should behave same on IPv6 (and do automatic configuration).
