netbase: add entry to /etc/hosts according to /etc/hostname

We default hostname to ${MACHINE}, but it's not in /etc/hosts, resulting in commands like `hostname -f' failing due to lack of entry.

So add entry to /etc/hosts according to /etc/hostname. We do this via pkg_postinst because hostname is set in base-files recipe.

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.

I'm torn on this as netbase is a much better fit for the hosts file and moving it would be a migration pain :(

Your other points stand though...
