Subject: Change how IPV4/IPV6 configuration values are done

1. Move vyatta-sysctl.conf from rl-system.init to procps
   This makes configuration happen early (before networking)

2. Do IPV6 configuration for address_flush in rl-system.init
   (after IPV6 is loaded)

3. Cleanup shell code for ipv6_params:
    * no sudo needed in startup scripts
    * use cleaner iteration
