wireguard does not output any buildversion , not on wg command or on
dmesg while loading,
this is low hanging fruit and make it particular easy to figure out
which version youre talking about,
and if i really have version 20160808 now, or still stuck on 20160722
(yes sorry, all my build experiments drive me crazy and confuse me a bit :)
(yes i know that ipk file , opkg mechanism tells me something about
version by its given name)
