net/yggdrasil-go: drop sample with random key, name readme after package

yggdrasil -genconf produces a working config, but everytime with a random key,
so every package built will differ. You're supposed to put your own key there
anyway (usually with yggdrasil-genkeys).

I don't see much value in shipping and installing a generated random config,
so drop that and expect the user to manager their /etc/yggdrasil.conf file,
if there should be any, themselves.

Next, the package is called yggdrasil-go, but the project's readme lands under
share/doc/yggdrasil/; not a big deal, but I think we usually go with PKGSTEM
for these, so adjust that, too.

Feedback? OK?
