Comment # 1 on bug 1142595 from Imobach Gonzalez Sosa

Fixed with https://github.com/yast/yast-yast2/pull/951 and
https://github.com/yast/yast-network/pull/906. The first PR should be enough
but, to be honest, the yast2-network module relies on /bin/hostname directly
so, strictly speaking, the dependency should be there.
