Subject: net: prefer /etc/hosts over DNS when no /etc/nsswitch.conf is present
References: gh#golang/go#35305 boo#1172868
Upstream: submitted

go standard library package net assumes file /etc/nsswitch.conf and does not
honor /usr/etc/nssswitch.conf location used in openSUSE. Upstream is reviewing a
fix to remove invalid the glibc DNS resolution assumption for go1.16 release
cycle scheduled for Februay 2021.
