This patch upgrades the collectd package from 5.7.2 to 5.8.2.
All openwrt patches got either updated or deleted in case they
are already included into upstream collectd.
The new collectd 5.8.0 package compiles and got tested on current
lede trunk with latest luci on an PCengines APU. All default plugins
(enabled via Openwrt  Makefile) - so also iwinfo - are running fine
with the new version.
