The uci config section network.globals set up in /bin/config_generate
will only be created if /proc/sys/net/ipv6 exists.
Correspondingly, lacking IPv6 support, the command
uci set network.globals.packet_steering=1
will fail with "uci: Invalid argument" as the network.globals config
has not been set up.
Fix that by adding the setup there as well.
Fixes: dfd62e575c ("ramips: enable packet steering by default on mt7621")
