[PATCH v3 14/14] fff-network: Migrate old settings

[Adrian Schmutzler]

This patch will migrate the custom settings from network.config
to the new configuration system.

The uci-default script only writes to /etc/firstbootfff, as this
is evaluated later in the uci-defaults run; it does not directly
apply any settings.
By writing to /etc/firstbootfff, the settings are still kept in
an upgrade-safe way.
