Subject: [PATCH] uts: Set default hostname to "localhost", rather than
 "(none)"

The "hostname" tool falls back to setting the hostname to "localhost" if
/etc/hostname does not exist.  Distribution init scripts have the same
fallback.  However, if userspace never calls sethostname, such as when
booting with init=/bin/sh, or otherwise booting a minimal system without
the usual init scripts, the default hostname of "(none)" remains,
unhelpfully appearing in various places such as prompts
("root@(none):~#") and logs.  Furthrmore, "(none)" doesn't typically
resolve to anything useful, while "localhost" does.

Change the default hostname to "localhost".  This removes the need for
the standard fallback, provides a useful default for systems that never
call sethostname, and makes minimal systems that much more useful with
less configuration.

Looked at "(none)" one too many times, and figured I ought to *do*
something about it.
