nss: Use "files dns" as the default for the hosts database (bug 28700)
This matches what is currently in nss/nsswitch.conf. The new ordering matches what most distributions use in their installed configuration files. It is common to add localhost to /etc/hosts because the name does not exist in the DNS, but is commonly used as a host name. With the built-in "dns [!UNAVAIL=return] files" default, dns is searched first and provides an answer for "localhost" (NXDOMAIN). We never look at the files database as a result, so the contents of /etc/hosts is ignored. This means that "getent hosts localhost" fail without a /etc/nsswitch.conf file, even though the host name is listed in /etc/hosts. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
