Stop using and copying the on-disk /etc/hosts file to the bsd.rd

/tmp dir during upgrade.

Create and use a minimal hosts file instead to avoid that a big
hosts file fills up the small bsd.rd / filesystem as reported
recently by Ted Roby.

Note that network interface configuration using hostnames instead
of ip addresses in hostname.if(5) relies on the on-disk /etc/hosts
file which is not used anymore during upgrade.
