Created a firewall chain for power save mode.
When power-save mode was first implemented, there were no firewall rules
on netd, so the solution was to make all network interface metered and
re-use the bw_penalty_box chain.
This change removes that workaround by creating a explicit fw_powersave
chain, whose behavior is similar to fw_dozable (in fact, it reuses some
of its code); such change not only makes network restrictions on
power-save mode simpler, but it also allows to optimze how the restrict
network rules are changed.
