[PATCH 3/4] systemd: add myhostname to nsswitch.conf

From: Christopher Larson <chris_larson@mentor.com>

We don't need nss-myhostname on systemd systems, because systemd already
provides myhostname, but we weren't configuring nsswitch to use it. Being able
to resolve the hostname is useful for a number of different applications, so
enable it using the same postinst/prerm bits which are in nss-myhostname.
