Wireguard fails on recent updates for OpenWRT on Turris Omnia, but same versions work on other (Linksys) routers with same CPU

openwrt doesnt use kernel 4.4 anymore for a long time. as far as i know 
it switched to 4.14 since some weeks
however the original omnis turria openwrt fork uses 4.4, but with 
different kernel configs. so you have to build wireguard
using exact the same sourcebase including kernel config, which is used 
in your omnis turria device

> Note that updates to the tools appear to be backported regularly to LEDE 17.01, but the kernel module appears to be as of the version available at the time of the release (17.01.5 in my case), so it isn’t unusual for these versions to not match as is the case here with mine. I’m not sure if the next release of OpenWrt will do a similar thing. It’d be nice if the kernel module updates were backported too.
