Drop the config knobs '*_address' and introduce '*_interface'
and '*_ipv6' instead.

'*_interface' takes an openwrt interface name ('loopback', 'lan',
'wan' etc), from which the primary IP is used to listen on. If
the matching '*_ipv6' is set to '1', the IPv6 adress will be used,
IPv4 elsewise.

procd interface triggers are now combined with this, so if a listen
interface is not yet configured when the init script is executed, the
process start is defered, and the trigger takes care of that once
the interfaces are ready.

This fixes the exact same build error reported at [0].
Upstream fixed it too, see [1], but I decided to use the minimal patch
until a new version is released instead.

statsd_exporter receives StatsD-style metrics and exports them as Prometheus
metrics.
