[OE-core] [PATCH 1/1] netbase: add entry to /etc/hosts according to /etc/hostname

[Burton, Ross]

What if the hostname entry already exists? $sysconfdir instead of
hard-coding etc.

I can't help but think a better solution would be to simply move
/etc/hosts to base-files, so it can be updated at the same time as
hostname.
