Consolidate sysupgrade.conf entries

Most of the entries in /etc/sysupgrade.conf are generated by a
uci-defaults script in the fff-sysupgrade package. The only entry
added in a different place is rc.local.fff_userconfig.

Consolidate all entries to be added by the uci-defaults script in
fff-sysupgrade.
