base-files: Drop localhost.localdomain from hosts file

This was likely something we took inspiration from elsewhere with.
It was added in:

https://git.openembedded.org/openembedded/commit/packages/netbase/netbase/hosts?id=c8e5702127e507e82e6f68a4b8c546803accea9d

in 2005. Debian added this entry around 2004 and discussed and dropped
it in 2005:

https://lists.debian.org/debian-devel/2005/10/msg00559.html

resulting in:

https://salsa.debian.org/installer-team/netcfg/-/commit/3c15ee521b2b8f47b34ccc7f610523cd284f2221

We should drop this for some of the reasons in those threads,
it doesn't seem to be doing anything too helpful and isn't what most
applications expect.
