Title: bump(coreos-base/coreos-init): Updates for empty /etc

Fix some issues for booting without using tmpfiles to setup the root
filesystem in advance. For example this now works reliably:

mkdir -p c/etc
cp /etc/os-release c/etc
ln -s usr/lib64 c/lib
ln -s usr/lib64 c/lib64
ln -s usr/bin c/bin
ln -s usr/sbin c/sbin
systemd-nspawn --directory=c --bind=/usr --boot
