If nsswitch.conf does not exist, create it with the default settings.

The reason for doing this is that (at least some) 4.x binaries are very
unhappy if host.conf does not exist, and if we create host.conf but not
nsswitch.conf, nsswitch.conf will be created at the next reboot, so it
is better to create a correct nsswitch.conf right away.
